Description

Technical Field

[0001] This utility model belongs to the field of dispensing machines and relates to a dispensing gun holder, specifically an easily adjustable dispensing gun holder for dispensing machines. Background Technology

[0002] Dispensing machines are widely used automated equipment in modern manufacturing. They are mainly used to precisely dispense, inject, or draw liquid PVC, silicone, and other fluids onto specific locations on workpieces to achieve functions such as dotting, drawing lines, and creating specific trajectories (such as circles and arcs). A typical dispensing machine usually includes a frame, a drive unit mounted on the frame, and a crossbar driven by the drive unit. Several dispensing gun holders are slidably mounted on the crossbar, each equipped with an independent adjustment device for adjusting and locking the position of the dispensing gun holder on the crossbar, thereby achieving precise control over the working point of an individual glue gun and the relative spacing between multiple glue guns. The glue guns are detachably mounted on the dispensing gun holders. During operation, the operator first adjusts the position of each glue gun according to the process requirements, and the drive unit drives all glue guns to perform synchronous movements, thus completing batch dispensing operations.

[0003] In the prior art, various dispensing gun holder structures have been proposed. For example, Chinese utility model patent with authorization announcement number CN222469593U discloses a dispensing gun holder that is clamped to the crossbar of the dispensing machine through an installation notch on its body, and locks or releases itself from the crossbar with the aid of a stop block, thereby completing the adjustment and fixation of its position.

[0004] However, in actual production applications, this type of structure presents significant operational inconveniences. Since the glue gun's glue line interface is typically located at its top and extends upwards, and the pneumatic tubing of the dispensing gun holder is also arranged at the top of the frame and runs upwards, the adjustment device, due to its function, must be located on the side of the dispensing gun holder closer to the crossbar. In other words, the adjustment device is located at the rear of the glue gun and dispensing gun holder. When multiple dispensing gun holders are densely arranged on the crossbar, if the operator needs to operate the adjustment device (such as the aforementioned abutment block) from the front of the glue gun, these intersecting glue and air lines often obstruct the operating area of ​​the adjustment device, making it difficult for the operator to make direct and convenient adjustments. This structural layout defect not only increases the difficulty and time of adjustment operations, reducing production efficiency, but also easily leads to misoperation during frequent adjustments, affecting the stability and accuracy of the dispensing process. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an easily adjustable dispensing gun holder, thereby making the adjustment of the adjustment device more convenient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An easily adjustable dispensing gun holder includes a frame body. The frame body has an installation notch at one end facing the crossbar. An adjusting block for clamping the crossbar is slidably disposed in the installation notch. The clamping and releasing of the crossbar by the frame body is achieved by changing the position of the adjusting block. The upper edge of the installation notch on the frame body is an inclined surface sloping upwards. The clamping block is disposed at one end of the installation notch near the upper edge, and the upper end surface of the clamping block is an inclined surface in the same direction as the inclined surface. A threaded adjusting member perpendicular to the inclined surface is disposed on the inclined surface. The lower end of the threaded adjusting member abuts against the upper end surface of the clamping block. Changing the position of the threaded adjusting member changes the height of the clamping block accordingly.

[0007] As a limitation of this utility model: the clamping block has an elongated hole along the height direction, and a fixing member is fixed on the frame and passes through the elongated hole. The clamping block can slide by the cooperation of the elongated hole and the fixing member.

[0008] As a limitation of this utility model: the fixing member is a bolt fixed to the frame in the horizontal direction, and the length of the smooth part of the bolt is adapted to the thickness of the clamping block.

[0009] As a limitation of this utility model: a clamping bolt along the height direction is detachably provided on the frame, and the end of the clamping bolt abuts against the end of the plug bolt.

[0010] As a limitation of this utility model: the two sides of the adjustment block in the width direction are fixed with sliding plates for sliding against the side wall of the frame, and the side wall of the frame is provided with a sliding groove adapted to the travel of the sliding plate.

[0011] As a limitation of this utility model: the lower edge of the inner wall of the mounting notch extends obliquely upward, and the lower edge of the clamping block extends obliquely downward, so that the clamping block and the mounting notch together form a dovetail groove.

[0012] As a limitation of this utility model: a U-shaped groove with an upward opening is provided in the middle of the frame, so that the frame is divided into a first frame near the crossbar and a second frame away from the crossbar by the U-shaped groove. The mounting notch and the adjusting block are provided on the first frame, and the glue gun is installed on the second frame.

[0013] As a limitation of this utility model: the second frame is provided with a first adjusting bolt that passes through the second frame in the direction of the U-shaped groove in the horizontal direction. After passing through the second frame, the first adjusting bolt is threadedly connected to the side wall of the first frame.

[0014] As a limitation of this utility model: the second frame is provided with a second adjusting bolt that passes through the second frame in the direction of the U-shaped groove in the horizontal direction. After the second adjusting bolt passes through the second frame, it abuts against the side wall of the first frame.

[0015] As a limitation of this utility model: both the first adjusting bolt and the second adjusting bolt are perpendicular to the crossbar and are located at the opening of the U-shaped groove.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) Effectively avoids pipeline obstruction, and the adjustment operation is convenient and efficient: By designing the upper edge of the mounting notch of the frame and the upper end face of the clamping block as inclined surfaces, the threaded adjustment component driving the clamping block is tilted forward as a whole. This structure allows the extended tool end to naturally extend from above the dense glue and air pipelines when using tools such as screwdrivers or hex wrenches, completely solving the problem of blind spots in adjustment caused by pipeline obstruction in the prior art. This not only significantly reduces the difficulty and time consumption of adjustment operations and improves the convenience and accuracy of adjustment, but also fundamentally improves the work efficiency in the production preparation stage; (2) It has an angle fine-tuning function, which significantly improves the dispensing accuracy: By setting the first and second adjusting bolts that cooperate with each other at the U-shaped groove structure, the clamping angle of the second frame (i.e. the part that installs the glue gun) can be finely and slightly adjusted. This design allows the operator to calibrate the straightness of the dispensing nozzle position of multiple glue gun heads on the same crossbar, ensuring that they can maintain a higher positional consistency during operation, thereby effectively improving the trajectory accuracy and product quality of batch dispensing.

[0017] In summary, this utility model can effectively avoid pipeline obstruction, is convenient and efficient in adjustment, and has an angle fine-tuning function, which significantly improves the dispensing accuracy. It is suitable for the installation and fixing of glue guns on drip molding machines. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the easily adjustable dispensing gun holder described herein is a preferred embodiment and is only used for illustration and explanation of the present invention, and does not constitute a limitation thereof.

[0022] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0023] This implementation example Figures 1-3 As shown, an easily adjustable glue gun holder includes a frame. During operation, several frames are slidably mounted on a crossbar 7 (in this embodiment, only one frame is mounted on the crossbar 7 to show the structure more clearly), and the glue gun 4 is mounted on the frame.

[0024] The frame has an upward-opening U-shaped groove 1 in the middle, which divides the frame into a first frame 2 that is relatively close to the crossbar 7 and a second frame 3 that is relatively far away from the crossbar 7. The structure for connecting and fixing with the crossbar 7 is set on the first frame 2, and the glue gun 4 is installed on the second frame 3.

[0025] A first adjusting bolt 5 is provided at the opening of the U-shaped groove 1 on the second frame 3. The first adjusting bolt 5 penetrates the second frame 3 and extends towards the U-shaped groove 1. The first adjusting bolt 5 is set horizontally and perpendicular to the crossbar 7 (i.e., along the length direction in the figure). After penetrating the second frame 3, the first adjusting bolt 5 is threadedly connected to the side wall of the first frame 2. This arrangement allows the depth of the first adjusting bolt inserted into the first frame 2 to be changed by screwing the first adjusting bolt 5, thereby bringing the first frame 2 and the second frame 3 closer together. Furthermore, a second adjusting bolt 6 is also provided at the opening of the U-shaped groove 1 on the second frame 3. The second adjusting bolt 6 is set one above the first adjusting bolt 5. The second adjusting bolt 6 penetrates the second frame 3 and extends towards the U-shaped groove 1. The second adjusting bolt 6 is set horizontally and perpendicular to the crossbar 7 (i.e., along the length direction in the figure). After penetrating the second frame 3, the second adjusting bolt 6 abuts against the side wall of the first frame 2. This configuration allows the first frame 2 and the second frame 3 to move away from each other by rotating the second adjusting bolt 6, relying on the contact force between the second adjusting bolt 6 and the side wall of the first frame 2. The first adjusting bolt 5 and the second adjusting bolt 6 work together to move the upper end of the second frame 3 closer to or further away from the first frame 2, thereby slightly adjusting the angle of the second frame 3 in the height direction, and consequently slightly adjusting the setting angle of the glue gun 4 mounted on the second frame 3, i.e., adjusting the relative position of the glue gun head.

[0026] The first frame 2 has an installation notch 8 at one end facing the crossbar 7. An adjusting block 9 for clamping the crossbar 7 is slidably disposed in the installation notch 8. The clamping and releasing of the crossbar 7 by changing the position of the adjusting block 9 is achieved by the frame. Specifically, the upper edge of the installation notch 8 on the first frame 2 is an upward inclined surface, that is, both the upper end surface of the first frame 2 and the upper end surface of the installation notch 8 are upward inclined surfaces. The clamping block is slidably disposed at one end of the installation notch 8 near the upper edge, and the upper end surface of the clamping block is an inclined surface in the same direction as the aforementioned inclined surface. A threaded adjusting member 10 perpendicular to the inclined surface passes through the upper edge of the installation notch 8, that is, the threaded adjusting member 10 is inclined towards the direction close to the second frame 3. In this embodiment, the threaded adjusting member 10 is a bolt. The lower end of the threaded adjusting member 10 is connected to the upper end of the clamping block. With the end faces abutting, when the threaded adjusting member 10 is screwed downwards, its lower end moves diagonally downwards, causing the clamping block to move downwards. This reduces the height of the mounting notch 8, allowing it to clamp the crossbar 7 and thus fix the relative position of the dispensing gun holder on the crossbar 7. When the threaded adjusting member 10 is screwed upwards, its lower end moves diagonally upwards, causing the clamping block to move upwards. This loosens the mounting notch 8 relative to the crossbar 7, allowing the dispensing gun holder to slide on the crossbar 7, facilitating adjustment of its position. During adjustment, the adjusting tool (such as a screwdriver, hex wrench, etc.) has a certain length, allowing its end to naturally extend above the dense adhesive and air lines, completely solving the problem of blind spots caused by pipe obstruction in existing technologies. Furthermore, the clamping block has two elongated holes 11 along the height direction. A fixing member 12, passing through the elongated holes 11, is fixed to the first frame 2. In this embodiment, the fixing member 12 is a threaded bolt fixedly installed on the frame along the length direction. The threaded bolt is an existing structure, comprising a bolt head, a smooth rod, and a threaded rod. In this embodiment, the threaded part of the threaded bolt is threaded onto the first frame 2. The length of the smooth rod is adapted to the thickness of the clamping block (i.e., the length direction dimension in the figure), allowing the smooth rod to function similarly to a slider. The elongated holes 11 of the clamping block function similarly to a crossbar 7. The clamping block slides along the height direction through the cooperation of the elongated holes 11 and the smooth rod. In other embodiments, the fixing member 12 can be replaced with other existing structures, such as bolts, as long as the relative position can be fixed and it functions similarly to a slider. To further secure the fastener 12, a clamping bolt 13 is detachably installed on the upper surface of the first frame 2 along the height direction. The lower end of the clamping bolt 13 directly abuts against the threaded part of the plug bolt to prevent the fastener 12 from loosening. To prevent the adjusting block 9 from tilting in the height direction during sliding, sliding plates 14 for sliding against the side wall of the frame are fixed on both sides of the adjusting block 9 in the width direction. A sliding groove 15 along the height direction is opened on the side wall of the frame, which is adapted to the stroke of the sliding plate 14. Here, "adapted" means that the highest height of the sliding groove 15 is equal to the highest height of the sliding plate 14, and the lowest height of the sliding groove 15 is equal to the lowest height of the sliding plate 14.

[0027] Furthermore, the lower edge of the inner wall of the mounting notch 8 extends obliquely upward, and the lower edge of the clamping block extends obliquely downward, so that the clamping block and the mounting notch 8 together form a dovetail groove. Correspondingly, the front side of the crossbar 7 is also a dovetail structure.

[0028] When using this embodiment, the tension of the first frame 2 relative to the crossbar 7 can be adjusted by adjusting the threaded adjusting part 10 with the adjusting tool. The position of the glue gun head can be adjusted slightly by adjusting the first adjusting bolt 5 and the second adjusting bolt 6 with the adjusting tool.

[0029] It should be noted that the improvement in this embodiment mainly lies in the use of the first adjusting bolt 5 and the second adjusting bolt 6 to achieve a small-scale adjustment of the glue gun head position, and the use of the inclined threaded adjusting member 10 to avoid obstruction of the glue path and air path during the adjustment operation. The specific structure of other parts of the frame, such as the glue gun 4 and other positions of the frame, can be adjusted as needed and is not limited to this embodiment.
