[0002] The working principle of the glue dispensing machine mainly includes the steps of glue supply, glue control, glue transmission, glue dispensing process and stopping glue dispensing. The glue delivery requires a hose to connect the glue dispensing head and the glue barrel, and the hose needs to be fixed to the glue dispensing machine frame with clamps, bolts and other components to prevent it from moving or offsetting during operation, ensuring a more stable flow of glue.

[0003] After searching, the Chinese patent publication number CN207308237U discloses a double-head clamp for a dispensing machine, including a dispensing machine frame, the front side wall of the dispensing machine frame is fixedly connected with two symmetrically arranged fixed clamps, and one end of a sliding rod is slidably connected in a strip groove opened in the front side wall of the dispensing machine frame, and the other end of the sliding rod is fixedly connected with a movable clamp corresponding to the fixed clamp, the lower end of the movable clamp is rotatably connected with one end of a clamping strip, the other end of the clamping strip is connected with a second conductive sheet, and the side wall of the clamping strip away from the movable clamp is connected with a metal spring through an air bag.

[0004] The above patent has the following shortcomings: it uses a movable splint, a clamping strip and an air bag to fix the hose, but the spacing between the clamping strip and the dispensing machine frame is constant, so it is impossible to clamp hoses of different diameters. When processing pipes of different sizes, the clamp needs to be replaced, which increases the complexity and time cost of the operation, resulting in low flexibility of the device.

[0005] Therefore, a double-head fixture for a dispensing machine is proposed. Utility Model Content

[0006] In view of this, the embodiment of the utility model hopes to provide a double-head clamp for a dispensing machine to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0009] In some embodiments, the top of the threaded rod is fixedly connected to a limiting plate, and the triangular plate is fixedly connected to the bottom of the threaded rod via a fixing rod.

[0010] In some embodiments, a receiving groove is formed on the inner wall of the connection block.

[0011] In some embodiments, the limiting assembly includes two symmetrically arranged sliding rods and a cam.

[0012] In some embodiments, the sliding rod is slidably fitted in the accommodating groove, one end of the sliding rod is fixedly connected to the second outer wall of the clamping plate, and the other end of the sliding rod is fixedly connected to the limiting ring.

[0013] In some embodiments, a spring is buckled on the side wall of the limiting ring, and the other end of the spring is buckled on the inner wall of the accommodating groove.

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-4 As shown, a double-head fixture for a glue dispensing machine includes a mounting plate 1 fixed to a frame of the glue dispensing machine by bolts, a support frame 2 fixedly connected to the bottom of the mounting plate 1 , and a connecting block 3 fixedly connected to the bottom of the support frame 2 .

[0032] A triangular plate 7 is provided inside the support frame 2, and symmetrical connecting rods 8 are rotatably connected to the two sides of the bottom of the triangular plate 7. The other end of the connecting rod 8 is rotatably connected to the connecting rod 2 9, and the other end of the connecting rod 2 9 is rotatably connected to the inner wall of the support frame 2, and a clamping plate 10 is fixedly connected to the outer wall of the bottom of the connecting rod 2 9, and both sides of the connecting block 3 are connected to the clamping plate 2 11 through a limit assembly.

[0033] When the triangular plate 7 moves downward, the cooperation of the connecting rod 1 8 and the connecting rod 2 9 can drive the clamping plate 10 to open to both sides. When the triangular plate 7 moves upward, the clamping plate 10 is retracted inwardly driven by the connecting rod 1 8 and the connecting rod 2 9, thereby changing the distance between the clamping plate 10 and the clamping plate 2 11, so that the clamping plate 10 and the clamping plate 2 11 can clamp hoses of different diameters.

[0034] The device is provided with a triangular plate 7, a connecting rod 1 8 and a connecting rod 2 9, which cooperate with each other to control the opening and closing angle of the clamping plate 10, thereby changing the distance between the clamping plate 10 and the clamping plate 2 11, so that the clamping plate 10 and the clamping plate 2 11 can clamp and fix hoses of different diameters, reducing the time and operation steps for replacing the clamps, and improving the flexibility of the device.

[0035] The device can complete the fixing of two hoses at one time by providing two symmetrically arranged clamping plates 10 and 11, thereby reducing the number of equipment replacements and improving operating efficiency.

[0036] like Figure 2As shown, the top of the mounting plate 1 is rotatably connected to a knob 4, the inner wall of the knob 4 is threadedly connected to a threaded rod 6, the top of the threaded rod 6 is fixedly connected to a limiting plate 5, and a triangular plate 7 is fixedly connected to the bottom of the threaded rod 6 through a fixing rod.

[0037] By rotating the knob 4, the threaded rod 6 can be driven to move up and down by the thread, thereby driving the triangular plate 7 to move up and down.

[0038] In this embodiment: the rubber hose is placed between the clamping plate 10 and the clamping plate 2 11, and then the knob 4 is rotated to make the threaded rod 6 move downward along the inner wall of the knob 4, driving the triangular plate 7 to move downward, and with the cooperation of the connecting rod 1 8 and the connecting rod 2 9, the two clamping plates 10 are retracted inward until the clamping plates 10 and the clamping plates 2 11 can completely clamp and fix the rubber hose, and then the knob 4 is stopped from being rotated; when the rubber hose needs to be removed, the knob 4 is rotated in the opposite direction, and the threaded rod 6 drives the triangular plate 7 to rise, so that the two clamping plates 10 are opened to both sides, and the distance between the clamping plates 10 and the clamping plates 2 11 is increased, so that the rubber hose can be removed at the same time.

[0039] Embodiment 2:

[0040] A double-head fixture for a dispensing machine. This embodiment makes the following improvements on the basis of embodiment 1: Figure 3 and Figure 4 As shown:

[0041] The inner wall of the connecting block 3 is provided with a receiving groove 17 .

[0042] The limit assembly includes two symmetrically arranged slide bars 12 and a cam 16 . The slide bar 12 is slidably fitted in the receiving groove 17 . One end of the slide bar 12 is fixedly connected to the outer wall of the second clamping plate 11 , and the other end of the slide bar 12 is fixedly connected to the limit ring 14 .

[0043] The side wall of the limiting ring 14 is buckled with a spring 13 , and the other end of the spring 13 is buckled with the inner wall of the accommodating groove 17 .

[0044] The cam 16 is rotatably connected to the inner wall of the receiving groove 17 through the damping shaft 15, and one end of the damping shaft 15 passes through the receiving groove 17 and the connecting block 3 and is fixedly connected to the handle 18. The outer wall of the connecting block 3 is provided with an arc-shaped limiting groove 19 for limiting the handle 18.

[0045] The cam 16 is rotated to rotate by the damping shaft 15, and the cam 16 protrusion is used to drive the limit ring 14 and the slide bar 12 to move toward the clamping plate 11, and the spring 13 is compressed by the force, and then the hose is placed in the groove of the clamping plate 11, and then the knob 4 is rotated, and the threaded rod 6, the triangular plate 7, the connecting rod 1 8 and the connecting rod 2 9 are used to make the clamping plate 10 move closer to the clamping plate 11, so that the hose is fixed. Since the device can clamp two hoses at a time, when only one hose needs to be removed, the corresponding handle 18 is rotated, so that the damping shaft 15 drives the cam 16 to rotate, so that the cam 16 protrusion leaves the limit ring 14, and the slide bar 12 and the clamping plate 11 are driven to move toward the cam 16 under the elastic force of the spring 13, thereby increasing the distance between the clamping plate 11 and the clamping plate 1 10, so that when the two hoses are fixed at the same time, one of the hoses can still be removed separately.

[0046] The device is provided with a cam 16, and the raised portion of the cam 16 can be used to push the clamping plate 11 outward, and cooperate with the clamping plate 10 to clamp the hose. When the handle 18 is rotated and the damping shaft 15 drives the raised portion of the cam 16 to leave the limit ring 14, the spring 13 can drive the clamping plate 11 to retract inward, thereby increasing the distance between the clamping plates 10 and 11, and then any one of the hoses can be removed separately according to needs, thereby improving the flexibility and convenience of the device.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
