Description

Technical Field

[0001] This application relates to the technical field of packaging equipment, and in particular to a terminal packaging machine. Background Technology

[0002] In the production and sales process of small terminals, after production is completed, the factory typically packages them all in plastic bags, with common packaging sizes such as fifty terminals per bag, before selling them to distributors. This packaging method is quite common in the market and can meet basic sales and transportation needs. However, in the terminal packaging stage, the usage of packaging machines can vary significantly due to market conditions. Market fluctuations directly affect order quantities, which in turn determine the frequency of packaging machine usage, leading to different situations regarding subsequent maintenance and use of the packaging machines.

[0003] Chinese patent application CN112173302A discloses a packaging machine with a counting function. The packaging machine includes a machine body with a feed inlet at its upper end and a feeding mechanism above the inlet. Within the feeding mechanism, a feed hopper is fixedly connected to a frame, and a conveyor belt is horizontally installed below the feed hopper. A counter is installed between the end of the conveyor belt away from the feed hopper and the machine body, and the counter is detachably connected to the upper surface of the machine body via a support frame. A discharge pipe is fixed below the counter, and a feeding assembly is installed below the discharge pipe on the machine body. In use, the product is injected into the feed hopper through the upper feed pipe, then conveyed to the counter by the conveyor belt, counted, and then enters the packaging machine body for packaging via the discharge pipe and feeding assembly.

[0004] In actual production applications, when market conditions are poor and orders are few, packaging machines in the factory often remain idle for extended periods. During this time, external dust accumulates and gradually adheres to the inner wall of the feed hopper, increasing over time. The problem becomes apparent when the feed hopper needs to be cleaned later to prevent dust from adhering to the products to be packaged. Because the feed hopper is located at a high position, workers must use climbing tools to reach the top and then use specialized cleaning tools to carry out the cleaning work. This process not only poses serious safety hazards but is also inefficient, time-consuming, and inconvenient for factory production management, urgently requiring improvement. Summary of the Invention

[0005] The purpose of this application is to provide a terminal packaging machine that solves the problems of safety hazards and low efficiency in the above-mentioned related technologies when cleaning the dust adhering to the inner wall of the feed hopper.

[0006] The terminal packaging machine provided in this application adopts the following technical solution: A terminal packaging machine includes a base and a packaging machine body fixed on the base. A counting hopper is fixedly installed on the upper side of the packaging machine body. A vertically upward frame is fixed on the base. A support frame is fixed horizontally above the base on the upper part of the frame. A conveyor belt with its discharge end located above the counting hopper is installed on the support frame. Vertically upward support plates are fixed on opposite sides of the support frame near the feed end of the conveyor belt. A feed hopper with its inlet facing upward and its outlet facing downward is provided between the two support plates. A rotating shaft is fixed on the two opposite vertical sides of the feed hopper and rotatably connected to the adjacent sides of the two support plates. A driving component is provided on the outer side of the support plate to drive the feed hopper to rotate around the rotating shaft. The feed inlet can be rotated to a protective state facing the discharge end of the conveyor belt and to an application state facing upward.

[0007] By adopting the above technical solution, rotating shafts connected to the support plate are set on the two opposite vertical sides of the feed hopper, and a drive component is provided to drive the feed hopper to rotate around the shafts. This allows the feed inlet to be switched between a protective state facing the conveyor belt discharge end and an upward application state. When the packaging machine is not in use, rotating the feed hopper to the protective state can effectively prevent external dust from entering the inner wall of the feed hopper, reducing dust accumulation at the source. This also avoids the need for workers to use climbing tools to work at height during subsequent cleaning due to the high position of the feed hopper, greatly reducing safety hazards.

[0008] Optionally, a vertically upward positioning plate parallel to the support plate is installed on the two opposite sides of the support frame, and a horizontally installed sealing plate is provided above the conveyor belt; the two opposite vertical sides of the sealing plate are detachably connected to the sides of the two positioning plates that are close to each other, and an adjusting brush is fixed on the bottom surface of the sealing plate, and a clearance gap is preset between the bottom surface of the adjusting brush and the upper side of the conveyor belt.

[0009] By adopting the above technical solution, a positioning plate is installed on the side of the support frame, and a sealing plate detachably connected to the positioning plate is used. This allows for flexible installation and removal of the sealing plate, facilitating maintenance and repair of internal components. An adjusting brush is installed on the bottom surface of the sealing plate, with a clearance between it and the conveyor belt. This allows the adjusting brush to clean any dust or debris that may adhere to the conveyor belt during operation, ensuring the cleanliness of the conveyor belt and the stability of terminal transmission. It also prevents the adjusting brush from excessively contacting the conveyor belt, which could affect its normal operation, thus improving the overall performance and packaging quality of the terminal packaging machine.

[0010] Optionally, the two vertical sides of the sealing plate are slidably connected to the sides of the two positioning plates that are close to each other, and a power component is fixed on the sides of the two positioning plates that are far apart from each other, which drives the sealing plate to slide back and forth along the length of the conveyor belt; when the feed inlet is in a protected state, the sealing plate can slide towards the feed hopper to block the feed inlet.

[0011] By adopting the above technical solution, when the feed inlet is in a protected state, the sealing plate can slide towards the feed hopper to seal it, further enhancing the dustproof effect and effectively preventing dust from entering the feed hopper during machine downtime, reducing subsequent cleaning work. Moreover, compared to other fixed or complex connection methods, the sliding connection method is simpler to install and disassemble, facilitating maintenance and replacement of the sealing plate. The power component automates the movement of the sealing plate, eliminating the need for manual operation. This not only saves manpower but also improves operational efficiency and accuracy, contributing to the overall stability and reliability of the terminal packaging machine and providing strong support for high-quality terminal packaging.

[0012] Optionally, a control plate is fixed horizontally on the side of the sealing plate facing the feed hopper; the upper surface of the control plate abuts against the bottom surface of the feed hopper in this state when the sealing plate blocks the feed inlet; the sealing plate can slide towards the feed hopper when the feed inlet is in the application state, and the control plate can abut against the opening edge of the discharge outlet at this time; the opening size of the discharge outlet is adjusted when the control plate slides back and forth.

[0013] By adopting the above technical solution, when the feed inlet is in use, the sealing plate slides to bring the control plate abutting against the edge of the discharge port opening, and the discharge port size can be adjusted by reciprocating sliding. This not only allows for flexible adjustment of the discharge volume according to the terminal specifications, ensuring packaging accuracy, but also enriches the functions of the packaging machine, enhances its adaptability to different production needs, and helps to improve production efficiency and product quality.

[0014] Optionally, a guide funnel with an upward opening is fixed to the upper opening edge of the counting hopper. The cross-sectional size of the guide funnel decreases along the direction close to the base. An outlet communicating with the interior of the counting hopper is provided on the bottom surface of the guide funnel.

[0015] By adopting the above technical solution, a guide funnel with an upward-facing opening and a cross-sectional size decreasing towards the base is provided along the upper edge of the counting hopper. This allows for better guidance of the terminals as they enter the counting hopper. When the terminals fall from above, the guide funnel accurately gathers them towards the outlet, reducing the likelihood of terminals scattering or getting stuck at the edge of the counting hopper. This ensures that the terminals smoothly enter the counting hopper for counting and packaging, improving the accuracy of counting and the smoothness of packaging.

[0016] Optionally, the counting hopper is provided with adjusting plates on its exterior. Two adjusting holes are provided on the two opposite vertical sides of the counting hopper, allowing the two adjusting plates to pass through each other at their respective ends. An elastic element is provided on the inner wall of the adjusting hole to drive the two adjusting plates to slide in opposite directions. A connecting member is provided on the exterior of the support frame. The positioning plate is slidably mounted on the upper side of the support frame. The positioning plate can slide back and forth along the length of the conveyor belt. A reset member is provided on the support frame to drive the positioning plate to slide towards the support plate and abut against it. When the sealing plate blocks the feed inlet in a protected state, it can continue to slide towards the feed hopper under the action of the power member. At this time, the positioning plate slides away from the support plate. The positioning plate, through the connecting member, drives the two adjusting plates to slide towards each other, thereby blocking the outlet.

[0017] By adopting the above technical solution, when the sealing plate slides further under the action of the power component to block the feed inlet, the positioning plate slides and drives the adjusting plate to slide in opposite directions through the connecting piece to block the outlet, thus achieving linkage sealing of the feed inlet and outlet. This not only enhances the overall dustproof effect when the packaging machine is not in use, preventing dust from entering the counting hopper and feed hopper and reducing subsequent cleaning work, but also completes the sealing action without additional complex operations through mechanical linkage, improving the convenience and automation of operation, effectively enhancing the overall performance of the terminal packaging machine, enabling it to better adapt to production needs under different working conditions, and ensuring the stability and efficiency of the production process.

[0018] Optionally, an adjustment groove is provided on the outer edge of the adjustment hole, and a first baffle is fixed on the outer periphery of the adjustment plate, which is inserted into the adjustment groove and slides back and forth. The elastic element is a first spring located in the adjustment groove, and the two ends of the first spring are fixedly connected to the bottom side of the adjustment groove and the inner side of the first baffle, respectively.

[0019] By adopting the above technical solution, an adjusting groove is formed at the outer edge of the adjusting hole opening, allowing the first baffle on the outer periphery of the adjusting plate to slide back and forth within it. A first spring serves as the elastic element, providing a stable and reliable guiding and resetting mechanism for the movement of the adjusting plate. The adjusting groove restricts the sliding trajectory of the first baffle, ensuring the adjusting plate performs precise linear reciprocating motion, preventing deviation or jamming, and making locking and unlocking actions smoother. The first spring deforms when the adjusting plate is moved under force, and quickly pulls it back to its original position after the external force disappears, achieving automatic reset.

[0020] Optionally, the reset component includes a second spring, a second baffle fixed to the positioning plate, and a fixed protrusion fixed to the support frame. The second baffle is located on the side of the fixed protrusion facing the support plate, and the two ends of the second spring are respectively fixedly connected to the sides of the protrusion and the second baffle that are close to each other.

[0021] By adopting the above technical solution, the second baffle is fixed to the positioning plate and cooperates with the fixed protrusion plate fixed to the support frame. The second spring connects the two, providing a stable and reliable reset force for the positioning plate. When the positioning plate slides away from the support plate under external force, the second spring is stretched and stores energy; after the external force disappears, the spring contracts, causing the positioning plate to automatically reset, ensuring the accuracy and stability of the positioning plate position. This enables the relevant linkage structure of the entire terminal packaging machine to operate reliably, improves the working accuracy and automation level of the equipment, and reduces the probability of failure.

[0022] Optionally, the connecting member includes a vertically downward connecting rod fixed on the side of the positioning plate away from the support plate, and a guide slope is provided on the outer edge of the adjusting plate; when the positioning plate abuts against the support plate, the connecting rod abuts against the vertical side of the support frame away from the support plate, and the lower end of the connecting rod is misaligned with the outer end of the adjusting plate at this time; when the positioning plate slides in the direction away from the support plate, the lower end of the connecting rod presses against the adjusting plate along the guide slope.

[0023] By adopting the above technical solution, when the positioning plate slides, the guide slope can smoothly convert the horizontal movement of the connecting rod into the compression of the adjusting plate, causing the adjusting plates to slide towards each other and achieving the sealing action of the outlet. This design utilizes the ingenious coordination of the mechanical structure to achieve precise linkage without complex control, improving the coordination and reliability between the various components of the equipment, and making the entire terminal packaging machine smoother and more stable in operation.

[0024] Optionally, a dovetail slide rail is fixed on the bottom surface of the positioning plate, and a dovetail groove is provided on the top surface of the support frame for the dovetail slide rail to be inserted and slid; an electromagnetic lock is provided on the dovetail slide rail, and a locking groove is provided on the bottom wall of the dovetail groove, and the locking tongue of the electromagnetic lock can be inserted into the locking groove when the positioning plate and the support plate abut.

[0025] By adopting the above technical solution, the bottom surface of the positioning plate is equipped with a dovetail slide rail that cooperates with the dovetail groove on the top surface of the support frame, providing precise guidance for the sliding of the positioning plate, ensuring its smooth movement and accurate positioning, reducing shaking and deviation, and improving the operational stability of the equipment. An electromagnetic lock is installed on the dovetail slide rail; when the positioning plate abuts against the support plate, the locking tongue inserts into the locking groove, firmly locking the positioning plate in position. This design combines mechanical guidance and electronic locking, ensuring both the flexibility of the positioning plate's movement and enhancing its stability during operation, thereby improving the overall reliability and safety of the terminal packaging machine.

[0026] In summary, this application includes the following beneficial technical effects: Rotating shafts, rotatably connected to the support plate, are installed on two opposite vertical sides of the feed hopper. These shafts are equipped with drive components to rotate the feed hopper around the shafts, allowing the feed inlet to be switched between a protected state facing the conveyor belt outlet and an upward-facing application state. When the packaging machine is not in use, rotating the feed hopper to the protected state effectively prevents external dust from entering the inner wall of the feed hopper, reducing dust accumulation at the source. This also avoids the need for workers to use climbing tools to perform subsequent cleaning due to the high position of the feed hopper, significantly reducing safety hazards.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] Example: Reference Figure 1 and Figure 2 A terminal packaging machine includes a base 1 and a packaging machine body 2 fixed on the base 1. A counting hopper 3 is fixedly installed on the upper side of the packaging machine body 2. A vertically upward frame 11 is fixed on the base 1. A support frame 4 located above the base 1 is fixed on the upper part of the frame 11 in a horizontal direction. A conveyor belt 12 with its discharge end located above the counting hopper 3 is installed on the support frame 4. The conveyor belt 12 is driven by a conventional motor fixed on the support frame 4, which will not be described in detail here. Vertical support plates 41 are integrally formed on opposite sides of the support frame 4 near the feeding end of the conveyor belt 12, and a feeding assembly 5 is installed between the two support plates 41. When the packaging machine is used, the material is transferred to the conveyor belt 12 through the feeding assembly 5, and then transferred to the counting hopper 3 through the conveyor belt 12, and then the workpiece is packaged by the packaging machine body 2.

[0032] Reference Figure 2 and Figure 3 The feeding assembly 5 includes a feeding hopper 51 with the feeding port 512 facing upward and the discharging port 513 facing downward. The two vertical sides of the feeding hopper 51 are fixed with rotating shafts 511 that are rotatably connected to the two support plates 41 close to each other. The support plates 41 are provided with driving components 52. The driving component 52 is a drive motor 521 fixed on the outer side of the support plate 41. The output shaft of the drive motor 521 passes through the support plate 41 and is coaxially fixedly connected to the rotating shaft 511. This will not be described in detail here. When the packaging machine is in use, the feed port 512 on the feed hopper 51 is rotated to the upward position using the drive component 52, at which time the material is normally injected into the feed hopper 51; when the packaging machine is stopped, the feed port 512 on the feed hopper 51 is rotated to the position facing the discharge end of the conveyor belt 12 to reduce the possibility of dust or other impurities adhering to the inner wall of the feed hopper 51.

[0033] Reference Figure 3 and Figure 4 The support frame 4 is provided with a sealing component 6 on its upper side. The sealing component 6 includes a positioning plate 61 installed on the opposite two sides of the support frame 4. The installation state of the positioning plate 61 satisfies both the conditions of being vertically upward and parallel to the support plate 41. A horizontally installed sealing plate 62 is provided above the conveyor belt 12. The two opposite vertical sides of the sealing plate 62 are detachably connected to the sides of the two positioning plates 61 that are close to each other. An adjusting brush 63 is fixed on the bottom surface of the sealing plate 62. A clearance gap is preset between the bottom surface of the adjusting brush 63 and the upper side of the conveyor belt 12. When workpieces are being transported on the conveyor belt 12 and there is an excessive accumulation of workpieces on a certain section of the conveyor belt 12, the adjusting brush 63 can be used to spread out the excessive workpieces on the same section of the conveyor belt 12, reducing the possibility of workpieces falling off the conveyor belt 12 due to excessive accumulation.

[0034] Reference Figure 3 , Figure 4 and Figure 5 An extension rod 621 is fixed on the two vertical sides of the sealing plate 62. A waist-shaped guide groove 611 is opened on the positioning plate 61 along the horizontal direction for the extension rod 621 to pass through and slide, so as to realize the sliding connection between the sealing plate 62 and the two positioning plates 61 on the sides close to each other. On the sides of the two positioning plates 61 that are far apart from each other, there is a power component 64 that drives the sealing plate 62 to slide back and forth along the length of the conveyor belt 12. Specifically, the power component 64 is a power electric cylinder 641 that is fixed on the positioning plate 61 in the horizontal direction. The output shaft of the power electric cylinder 641 is fixedly connected to the end of the extension rod 621. When the feed inlet 512 is in a protected state, the sealing plate 62 can slide towards the feed hopper 51 under the action of the power cylinder, thereby sealing the feed inlet 512 on the feed hopper 51 and reducing the possibility of external dust or other impurities adhering to the inner wall of the feed hopper 51 in this state.

[0035] Reference Figure 3 and Figure 5 A control plate 65 is fixed horizontally on the side of the sealing plate 62 facing the feed hopper 51. When the feed hopper 51 is in a protected state and the sealing plate 62 blocks the feed inlet 512, the upper side of the control plate 65 abuts against the bottom surface of the feed hopper 51 in this state and is limited. When the feed hopper 51 is in the state where the feed inlet 512 is facing upward, the sealing plate 62 can be controlled to slide towards the feed hopper 51. At this time, the control plate 65 can abut against the edge of the outlet 513. When the control plate 65 slides back and forth, the opening size of the outlet 513 is adjusted.

[0036] Reference Figure 6 and Figure 7 The upper side opening edge of the counting hopper 3 is fixed with an upward-facing guide funnel 7, wherein the cross-sectional dimension of the guide funnel 7 decreases along the direction close to the base 1, and an outlet 71 communicating with the interior of the counting hopper 3 is provided on the bottom surface of the guide funnel 7.

[0037] Reference Figure 7 and Figure 8 The counting bucket 3 is provided with an adjusting member 8, which includes two adjusting plates 81 disposed opposite to each other on the outside of the counting bucket 3. Two adjusting holes 31 are provided on the two opposite vertical sides of the counting bucket 3 for the two adjusting plates 81 to pass through the ends of the two adjusting plates 81 respectively. The inner wall of the adjusting hole 31 is provided with an elastic member 82 that drives the two adjusting plates 81 to slide in opposite directions. The support frame 4 is provided with a connecting member 83 on the outside. The positioning plate 61 is slidably mounted on the upper side of the support frame 4. The positioning plate 61 can slide back and forth along the length of the conveyor belt 12. The support frame 4 is provided with a reset member 66 that drives the positioning plate 61 to slide closer to the support plate 41 and abuts against the positioning plate 61. When the sealing plate 62 blocks the feed inlet 512 which is in a protected state, the sealing plate 62 can continue to slide towards the feed hopper 51 under the action of the power component 64. At this time, the positioning plate 61 overcomes the squeezing force of the reset component 66 and slides away from the support plate 41. The positioning plate 61 drives the two adjusting plates 81 to slide towards each other through the connecting component 83, thereby blocking the outlet 71. That is, when the feed inlet 512 is blocked, the outlet 71 on the guide funnel 7 is blocked simultaneously.

[0038] Reference Figure 8 and Figure 9 An adjustment groove 32 is provided on the outer edge of the adjustment hole 31. A first baffle 811 is fixed on the outer periphery of the adjustment plate 81, which is inserted into the adjustment groove 32 and slides back and forth. The elastic element 82 is a first spring 821 located in the adjustment groove 32. The two ends of the first spring 821 are fixedly connected to the bottom side of the adjustment groove 32 and the inner side of the first baffle 811, respectively.

[0039] Reference Figure 7 and Figure 8The connecting member 83 includes a vertically downward connecting rod 831 fixed on the side of the positioning plate 61 away from the support plate 41, wherein the outer edge of the adjusting plate 81 is provided with a guide slope 812; when the positioning plate 61 abuts against the support plate 41, the connecting rod 831 abuts against the vertical side of the support frame 4 away from the support plate 41, and at this time the lower end of the connecting rod 831 is misaligned with the outer end of the adjusting plate 81; when the positioning plate 61 slides in a direction away from the support plate 41, the lower end of the connecting rod 831 presses against the adjusting plate 81 along the guide slope 812, so that the two adjusting plates 81 slide towards each other to the abutting state, thereby blocking the outlet 71.

[0040] Reference Figure 10 The reset member 66 includes a second spring 661 in a compressed state, a second baffle 662 fixed on the positioning plate 61, and a fixed protrusion 663 fixed on the support frame 4. The second baffle 662 is located on the side of the fixed protrusion 663 facing the support plate 41. The two ends of the second spring 661 are fixedly connected to the sides of the protrusion 663 and the second baffle 662 that are close to each other.

[0041] Reference Figure 10 The bottom surface of the positioning plate 61 is fixed with a dovetail slide rail 612, and the top surface of the support frame 4 is provided with a dovetail groove 42 for the dovetail slide rail 612 to be inserted and slid, so as to realize the sliding connection between the positioning plate 61 and the support frame 4; the dovetail slide rail 612 is provided with an electromagnetic lock 67, and the bottom wall of the dovetail groove 42 is provided with a locking groove 421. The electromagnetic lock 67 is a conventional locking structure, and its specific structure will not be described in detail here. When the positioning plate 61 abuts against the support plate 41, the locking tongue of the electromagnetic lock 67 can be inserted into the locking groove 421. At this time, the sealing plate 62 drives the adjusting brush 63 to slide more stably, thereby improving the installation stability of the positioning plate 61.

[0042] The implementation principle of this application embodiment is as follows: When the packaging machine is used, the drive unit 52 is used to make the feed port 512 of the feed hopper 51 face upward, and the material is injected normally. The material is transferred to the counting hopper 3 by the conveyor belt 12, and then packaged by the packaging machine body 2. When too many workpieces are piled up on the conveyor belt 12, the sealing plate 62 can drive the adjusting brush 63 to slide, thereby spreading them out and preventing the workpieces from falling out. The positioning plate 61 and the support frame 4 are slidably connected by the dovetail slide rail 612 and the dovetail slide groove 42. When the positioning plate 61 abuts against the support plate 41, the locking tongue of the electromagnetic lock 67 is inserted into the locking groove 421, which can improve the installation stability of the positioning plate 61 and ensure that the sealing plate 62 drives the adjusting brush 63 to slide more stably. During the sliding process of the sealing plate 62, the control plate 65 can abut against different parts of the feed hopper 51 to adjust the opening size of the discharge port 513.

[0043] When the packaging machine stops, the drive unit 52 moves the feed inlet 512 of the feed hopper 51 toward the discharge end of the conveyor belt 12, reducing the possibility of dust and other particles adhering to the inner wall. At this time, the power unit 64 drives the sealing plate 62 to slide toward the feed hopper 51, blocking the feed inlet 512. Then the sealing plate 62 slides further, causing the positioning plate 61 to overcome the squeezing force of the reset unit 66 and slide away from the positioning plate 61. Finally, the connecting member 83 drives the two adjusting plates 81 to slide toward each other, blocking the outlet 71 of the guide funnel 7, further reducing the entry of dust and other particles.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
