Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to an adjustable cardboard box counting device. Background Technology

[0002] In industrial production, counting is a core foundational step throughout the entire process, from raw material control and processing to finished product accounting. Its accuracy directly determines the reliability of production data statistics and has a crucial impact on factory cost accounting, capacity planning, and production efficiency optimization. In traditional production scenarios, manual counting methods generally suffer from drawbacks such as low efficiency, susceptibility to errors, and high labor intensity, making it difficult to meet the precision management needs of large-scale production. With the rapid development of electronic information technology and sensor technology, counting methods have gradually evolved from manual to automated processes. Electronic counting equipment, with its advantages of high efficiency, accuracy, and continuous operation, has been widely used in various manufacturing plants. Among these advancements, breakthroughs in sensor technology have brought revolutionary improvements to counting equipment. Through non-contact detection and real-time signal feedback, it has significantly improved the stability and anti-interference capabilities of counting, becoming the mainstream technical solution for counting in modern industrial production.

[0003] In cardboard box processing, the counting process is equally crucial. Based on this need, cardboard box processing plants have widely adopted electronic counting equipment to replace traditional manual counting. The current mainstream equipment structure is typically a combination of a support frame and a counter. The support frame is fixedly installed above the conveyor belt. When a cardboard box passes through the counter's detection area with the conveyor belt, the counter automatically completes the counting operation. For example, the "Packaging Counting Equipment for Cardboard Box Processing" disclosed in publication number CN221542192U has a core structure including a base, support components, and a counting box. The counting box is mounted on top of the conveyor device via the support components to achieve the counting function. Although existing electronic counting equipment has solved the efficiency and accuracy problems of manual counting, its support structure design has significant limitations in practical applications, resulting in extremely low equipment adaptability. The supports of existing equipment are mostly fixed-size structures, only compatible with conveyor devices of specific widths and heights. In other words, the support frame needs to be customized or modified according to the specific dimensions of the on-site conveyor device. When a factory replaces its conveyor systems with different specifications, such as adjusting the conveyor belt width to produce different sized cartons, the existing counting equipment's support frame cannot be adapted to the new device. A new support frame needs to be custom-made, which not only increases equipment procurement and modification costs but also disrupts production continuity due to the equipment replacement cycle. Therefore, it is necessary to develop a carton counting device with an adjustable support structure that can be adapted to various sizes of conveying devices. Utility Model Content

[0004] To address the above shortcomings, this utility model provides an adjustable carton counting device, whose support frame can be adjusted to adapt to different conveying devices as needed, thus having higher adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable carton counting device includes an electronic counter, a base, elastic adjustment components, locking parts, and fixed clamps. The electronic counter is mounted on the base. Four sets of elastic adjustment components are symmetrically installed in pairs on both sides of the lower part of the base. Two fixed clamps are located at both ends of the base and movably mounted on the elastic adjustment components on the same side. Four sets of locking parts are correspondingly installed on both sides of the two fixed clamps to lock the elastic adjustment components relative to each other. The elastic adjustment components can be adjusted to a suitable size as needed. The fixed clamps are mounted on the elastic components, and the elastic adjustment components drive the fixed clamps to clamp the conveying device, thereby fixing the entire device in place.

[0006] Preferably, the elastic adjustment assembly includes a movable rod, a connecting ball, a first spring, and a fixed rod. Slide grooves are provided on both sides of the lower part of the base, and first limiting holes are provided on both sides of the slide grooves. The lower part of the slide grooves penetrates the lower part of the base. A pair of movable rods are symmetrically arranged in each slide groove. A first mounting thread is provided on the side of the movable rod that passes through the first limiting hole. The connecting ball has a threaded hole matching the first mounting thread and is fitted onto the movable rod. The fixed rod is fixed to the lower part of the connecting ball. A fixed clamping plate is installed on the fixed rod for limiting. A limiting block is provided at one end of the movable rod located in the slide groove. The first spring is sleeved on the movable rod and located between the limiting block and the first limiting hole. By changing the length of the elastic adjustment assembly extending from the base, it can adapt to the size of different sized transmission devices. At the same time, the spring's rebound force will pull the fixed rod towards the base, thereby causing the fixed clamping plate to clamp the transmission device.

[0007] Preferably, the upper part of the base is provided with a mounting groove that matches the shape of the electronic counter, and the base is detachably limited and installed in the mounting groove, which facilitates the installation and removal of the electronic counter.

[0008] Preferably, the middle of the slide groove is also provided with an assembly groove, which can accommodate the limit block to pass through. When assembly is required, the side of the movable rod with the circular limit block is inserted into the slide groove through the assembly groove. The entire movable rod with the first spring is then inserted into the slit under the slide groove and extends out from the first limit hole. The diameter of the limit hole is larger than the diameter of the movable rod but smaller than the diameter of the limit block. The connecting ball with the fixed rod is fastened to the movable rod with the first installation thread through the screw hole. Then, the fixed rod is adjusted to be inserted vertically downwards into the fixed clamping plate.

[0009] Preferably, the fixing plate is a T-shaped plate with two insertion holes at both ends. The flat side of the T-shaped plate is mounted on the fixing rods of two sets of elastic components on one side of the base. A mounting plate is provided on the side of the T-shaped plate away from the base, and locking components are arranged laterally on the mounting plate at the two insertion holes. The T-shaped plate design facilitates clamping of the conveying device. The locking components cooperate with the fixing rods to lock the fixing rods, and the height of the fixing rods can be adjusted to accommodate cartons of different sizes.

[0010] Preferably, the locking component includes a locking rod, a second spring, a nut, and a lock head. The lock head is fixed to one end of the locking rod, and the other end is provided with a second mounting thread. The mounting plate has mounting holes at two insertion positions, and a second limiting hole is provided at the bottom of the mounting holes. The end of the locking rod with the second mounting thread passes through the second limiting hole, and the nut is fitted onto the second mounting thread. The second spring is sleeved on the locking rod and located between the lock head and the second limiting hole. The fixing rod has multiple locking holes evenly arranged longitudinally for use with the lock head. This design makes it easier to lock the fixing rod. During operation, only two actions are required: loosening and pulling the nut. The fixing rod can be locked by engaging the locking holes, making it more convenient and faster.

[0011] Preferably, a rubber pad is provided on the right-angled side of the lower part of the T-shaped plate near the base. This further enhances the anti-slip performance.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable carton counting device, through the structure of four sets of elastic adjustment components symmetrically installed in pairs on both sides of the lower part of the base, and two fixed clamps movably installed on the elastic adjustment components on the same side, can flexibly adjust the spacing of the fixed clamps according to the width of different conveying devices. When the fixed clamps are pulled, the elastic adjustment components deform accordingly to adapt to the width change. After being released, the rebound force of the elastic components can drive the fixed clamps to clamp the conveying device. There is no need to customize or modify the bracket for different specifications of conveying devices, which greatly reduces the cost of equipment purchase and modification. At the same time, it avoids production interruption caused by equipment replacement, fully meets the needs of flexible adjustment of conveying device specifications in large-scale factory production, and significantly improves the adaptability of the equipment to different production scenarios.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] This embodiment provides an adjustable carton counting device, such as... Figures 1-6 As shown, the device is equipped with a base 1, which serves as the basic support component of the entire device. The base 1 has an upper mounting groove 101 that perfectly matches the shape of the electronic counter 2 to be installed later. The depth of the mounting groove 101 is adapted to the thickness of the electronic counter 2, ensuring that the electronic counter 2 can be stably embedded. The electronic counter 2 is detachably and securely installed within the mounting groove 101. Specifically, this can be achieved by setting elastic buckles on the inner wall of the mounting groove 101. This is existing technology and is not shown in the figure. When the electronic counter 2 is placed into the mounting groove 101, the elastic buckles can lock the sides of the electronic counter 2, enabling quick installation and removal. The electronic counter 2 is used to count and detect passing cartons. The base 1 has symmetrically arranged sliding grooves 102 on both sides of its lower part. The sliding grooves 102 extend along the length of the base 1 and penetrate the lower part of the base 1 to form an open structure. At the same time, the base 1 wall on both sides of the sliding grooves 102 is provided with corresponding first limiting holes 103. The first limiting holes 103 are connected to the inside of the sliding grooves 102, and the diameter of the first limiting holes 103 is smaller than the width of the sliding grooves 102. The middle part of the sliding grooves 102 is also provided with an assembly groove 104. The width of the assembly groove 104 is larger than the size of the upper limit block 302 of the subsequent movable rod 301, which can accommodate the limit block 302 to pass through smoothly, facilitating the assembly of the movable rod 301. A pair of movable rods 301 are symmetrically arranged in the sliding grooves 102 on both sides of the lower part of the base 1. The movable rods 301 are cylindrical rods with a length greater than the length of the sliding groove 102. One end of the movable rod 301 extends into the sliding groove 102, and a limiting block 302 is fixed to the extended end. The limiting block 302 is a circular block structure with a diameter greater than the diameter of the first limiting hole 103 and smaller than the width of the sliding groove 102. It can slide along the length direction in the sliding groove 102 but cannot pass through the first limiting hole 103. The other end of the movable rod 301 passes through the first limiting hole 103. 3 extends to the outside of the base 1, and the outer surface of the extended end is machined with a first mounting thread 303; a first spring 304 is sleeved on the rod body of the movable rod 301 located in the slide groove 102. One end of the first spring 304 abuts against the side of the limiting block 302 away from the extended end of the movable rod 301, and the other end abuts against the edge of the first limiting hole 103 on the inner side wall of the slide groove 102. When the movable rod 301 slides along the slide groove 102 under the action of external force, the first spring 304 can generate elastic deformation, and can drive the movable rod 301 to reset after the external force disappears.

[0020] A connecting ball 305 is installed at one end of the movable rod 301 extending to the outside of the base 1. The connecting ball 305 is a solid spherical structure with a screw hole at its center that matches the first mounting thread 303 on the movable rod 301. The connecting ball 305 is threadedly engaged with the first mounting thread 303 on the movable rod 301 through the screw hole to achieve a fixed connection with the movable rod 301. The connecting ball 305 is used to achieve a transition connection between the movable rod 301 and the subsequent fixed rod 306, and can adjust the angle of the fixed rod 306 within a certain range. A fixed rod 306 is fixedly connected to the lower part of the connecting ball 305. The fixed rod 306 is a cylindrical rod, and its axis is on the same straight line as the center of the connecting ball 305. The fixed rod 306 and the connecting ball 305 are fixed by welding or integral molding to ensure the connection strength. The fixed rod 306 is used to install the fixed clamp 4. Two fixing plates 4 are provided, each of which is a T-shaped plate 401. The T-shaped plate 401 includes a horizontal flat plate portion and a vertical plate portion. Two insertion holes 402 are provided at both ends of the flat plate portion. The diameter of the insertion holes 402 is adapted to the diameter of the fixing rod 306. The T-shaped plate 401 is installed on the fixing rods 306 of the two sets of elastic adjustment components 3 on one side of the base 1 with the flat side facing upward. Specifically, the end of the fixing rod 306 away from the connecting ball 305 is inserted into the insertion hole 402 of the flat plate portion of the T-shaped plate 401 to achieve the limiting installation of the fixing plate 4 and the fixing rod 306. The fixing plate 4 is used to connect with the side of the conveying device. The components are fitted together to fix the entire device to the conveying device; a mounting plate 403 is fixedly connected to the vertical plate part of the T-shaped plate 401 away from the base 1. The mounting plate 403 is a rectangular plate body, which is set perpendicular to the vertical plate part of the T-shaped plate 401. The mounting plate 403 has horizontally opened mounting holes 405 at the positions corresponding to the two insertion holes 402 on the flat plate part of the T-shaped plate 401. The mounting holes 405 have a stepped hole structure, with the upper hole diameter being larger than the lower hole diameter. A second limiting hole 406 is opened at the bottom of the mounting hole 405. The second limiting hole 406 is coaxial with the mounting hole 405, and the hole diameter of the second limiting hole 406 is smaller than the upper hole diameter of the mounting hole 405. A locking component 5 is installed in the mounting hole 405 of the mounting plate 403. Four sets of locking components 5 are provided, each corresponding to a mounting hole 405 on either side of the two fixed clamping plates 4. The locking component 5 includes a locking rod 501, a second spring, a nut 504, and a lock head 503. The lock head 503 has a conical structure, with its bottom surface fixed to one end of the locking rod 501. The conical surface of the lock head 503 facilitates subsequent insertion into the locking hole 307 on the fixed rod 306. The locking rod 501 is a cylindrical rod, with a second mounting thread 502 machined on the outer surface of its other end. The locking rod 501 is installed in the mounting hole 405 of the mounting plate 403, with the length of the locking rod 501 exceeding the depth of the mounting hole 405. The locking rod 501 has a second mounting thread 502. One end of the lock rod 501 extends through the second limiting hole 406 at the bottom of the mounting hole 405 to the rear of the mounting plate 403, and the diameter of the second limiting hole 406 is smaller than the bottom diameter of the lock head 503; a second spring is sleeved on the rod body of the lock rod 501 located in the mounting hole 405, one end of the second spring abuts against the bottom surface of the lock head 503, and the other end abuts against the edge of the second limiting hole 406 at the bottom of the mounting hole 405; a nut 504 is fitted on the second mounting thread 502 extending from the lock rod 501 to the rear of the mounting plate 403. By tightening the nut 504, the second spring can be compressed, causing the lock head 503 to approach the bottom of the mounting hole 405. By loosening the nut 504, the second spring returns to its original position, pushing the lock head 503 out of the mounting hole 405. For the lock head 503 corresponding to the locking component 5, multiple lock holes 307 are evenly provided longitudinally on the rod body of the fixing rod 306. The diameter of the lock hole 307 is adapted to the diameter of the lock head 503. When the fixing rod 306 is inserted into the insertion hole 402 of the T-shaped plate 401, the insertion depth of the fixing rod 306 is adjusted so that the lock head 503 can be aligned with one of the lock holes 307. At this time, under the action of the second spring, the lock head 503 can be inserted into the lock hole 307, realizing the relative fixation of the fixing rod 306 and the fixing clamp 4, preventing the fixing rod 306 from moving up and down in the insertion hole 402. When it is necessary to adjust the height of the fixing rod 306, simply pull the locking rod 501 outward to disengage the lock head 503 from the lock hole 307. After adjusting the fixing rod 306 to a suitable height, release the locking rod 501, and the lock head 503 can be reinserted into the corresponding lock hole 307 under the action of the second spring to complete the locking. In addition, a rubber pad 404 is fixed on the right-angle side of the lower part of the T-shaped plate 401 near the base 1. The rubber pad 404 is made of elastic rubber and is fixed to the right angle of the T-shaped plate 401 by adhesive. When the fixing clamp 4 is in contact with the side of the conveying device, the rubber pad 404 can increase the friction between the device and the conveying device, prevent the device from sliding, and avoid hard contact between the fixing clamp 4 and the conveying device, thus protecting the surface of the conveying device from being scratched. The aforementioned base 1, electronic counter 2, elastic adjustment components 3, fixed clamps 4, and locking components 5 together constitute an adjustable carton counting device. The elastic adjustment components 3 consist of four sets, symmetrically installed in pairs on both sides of the lower part of the base 1. Two fixed clamps 4 are located at both ends of the base 1 and are movably mounted on the fixed rods 306 of the two sets of elastic adjustment components 3 on the same side. The four sets of locking components 5 are correspondingly installed on the mounting plates 403 on both sides of the two fixed clamps 4, achieving relative locking of the elastic adjustment components 3. In use, according to the width of the conveying device, the fixed clamps 4 on both sides are pulled, causing the movable rod 301 to slide along the slide groove 102. The first spring 304 is compressed, and the fixed clamps 4 are pressed against both sides of the conveying device. After releasing the fixed clamps 4, the first spring 304 returns to its original position, causing the movable rod 301 to pull the fixed clamps 4 to clamp the conveying device. Then, the height of the fixed rod 306 is locked by the locking components 5, thus completing the installation and fixing of the device, adapting to conveying devices of different sizes.

[0021] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
