Description

Technical Field

[0001] The utility model relates to a processing device for glass tubes, in particular to a clamping mechanism for a row of glass tubes. Background Art

[0002] The production and packaging of glass tubes are widely used in the market. A glass tube drawing device is provided with a tube cutting device at the outlet of the tube drawing port to cut the drawn and formed glass tubes into glass tubes of almost the same length. Due to the poor accuracy of the tube cutting device, the length deviation of the cut glass tubes is relatively large. Therefore, generally, a tube aligning device needs to be set after tube cutting to cut off a small section of the glass tube again to make the length of each glass tube consistent, that is, end trimming processing, which is convenient for subsequent packaging and transportation. However, this also wastes a certain amount of materials and increases the processing procedures. Summary of the Invention

[0003] Aiming at the above existing technical problems, the utility model provides a clamping mechanism for a row of glass tubes, which can realize the subsequent clamping, transportation and packaging of the row of glass tubes without end trimming processing.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: A clamping mechanism for a row of glass tubes includes a main frame, a clamping driving mechanism and a clamping mechanism; the clamping driving mechanisms are arranged in pairs on both sides of the main frame mechanism; the clamping mechanisms are arranged in pairs on both sides of the main frame mechanism, and the clamping mechanism includes a main clamping plate, a cylinder seat, a cylinder, a lower supporting plate and an auxiliary clamping plate; the main clamping plate is connected with the clamping driving mechanism and can be driven by the clamping driving mechanism to move simultaneously towards the inner side of the main frame mechanism to clamp the row of glass tubes, or move simultaneously towards the outer side of the main frame mechanism to release the row of glass tubes; the auxiliary clamping plate is connected below the main clamping plate, the cylinder seat is fixed at the lower part of the auxiliary clamping plate, the cylinder is fixed on the cylinder seat, the lower supporting plate is arranged at the bottom of the auxiliary clamping plate, and the lower supporting plate is connected with the rod seat of the cylinder and can move reciprocally with the cylinder. When the main clamping plate clamps, the lower supporting plate extends out to support the clamped row of glass tubes, and when the main clamping plate releases, the lower supporting plate retracts to put down the row of glass tubes.

[0005] Further, the clamping driving mechanism of the utility model includes a servo motor, a coupling, a transmission lead screw, a transmission nut, a motor mounting seat, a nut mounting seat, a slider and a slide rail; the servo motor is fixed on the main frame through the motor mounting seat, the servo motor drives the transmission lead screw, there is a nut on the transmission lead screw, the nut is fixed on the slide rail through the nut mounting seat, the slider is fixed on the main frame, and the slide rail is slidably arranged in the slider.

[0006] Further, on both sides of the main clamping plate, there are main clamping plate sliders which are slidably arranged on the slide rail. On the slide rail inside the main clamping plate, there is a positioning block, and a tension spring is connected between the positioning block and the main clamping plate to tighten the main clamping plate towards the positioning block.

[0007] Further, on both sides of the lower part of the auxiliary clamping plate, there are side baffles which, when the lower supporting plate extends out, form a bucket shape together with the lower supporting plate.

[0008] Further, on the back of the auxiliary clamping plate, there are a pair of auxiliary clamping plate slide rails. Corresponding to these on the main clamping plate, there are auxiliary clamping plate sliders. The auxiliary clamping plate slides up and down within the auxiliary clamping plate sliders through the auxiliary clamping plate slide rails. Between the auxiliary clamping plate sliders, there are an upper stop block and a lower stop block. Between the auxiliary clamping plate slide rails, there is a limit block which moves between the upper stop block and the lower stop block to limit the moving range of the auxiliary clamping plate.

[0009] Further, at the center top of the main frame mechanism, there is a hoisting connection pipe.

[0010] The beneficial effects of adopting the above technical solution are as follows: The present utility model adopts a clamping mechanism with a lower supporting plate. The lower supporting plate itself has a certain length and can place a row of glass tube products with slightly different lengths. This enables the glass tube packaging machine with this mechanism to realize the subsequent clamping, transportation, and packaging of the glass tube row without performing end trimming processing. In this way, while reducing the processes, it also saves materials, saving both processing and material costs for glass tube manufacturers. Description of the Drawings

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] An embodiment of the present utility model: As Figure 1 shown, a glass tube row clamping mechanism includes a main frame 0100, a clamping drive mechanism 0200, and a clamping mechanism 0300; the clamping drive mechanisms 0200 are arranged in pairs on both sides of the main frame mechanism 0100. As Figure 3 and Figure 4 shown, the clamping mechanisms 0300 are arranged in pairs on both sides of the main frame mechanism 0100. The clamping mechanism 0300 includes a main splint 0302, a cylinder seat 0305, a cylinder 0306, a lower support plate 0307, and a sub-splint 0309; the main splint 0302 is connected to the clamping drive mechanism 0200 and can be driven by the clamping drive mechanism 0200 to move inward towards the main frame mechanism 0100 simultaneously to clamp the glass tube row 0400, or move outward towards the main frame mechanism 0100 simultaneously to release the glass tube row 0400; the sub-splint 0309 is connected below the main splint 0302, the cylinder seat 0305 is fixed at the lower part of the sub-splint 0309, the cylinder 0306 is fixed on the cylinder seat 0305, the lower support plate 0307 is arranged at the bottom of the sub-splint 0309, and the lower support plate 0307 is connected to the rod seat of the cylinder 0306 and can reciprocate with the cylinder 0306. When the main splint 0302 clamps, the lower support plate 0307 extends to support the clamped glass tube row 0400, and when the main splint 0302 releases, the lower support plate 0307 retracts to put down the glass tube row 0400.

[0023] The specific working process is as follows: The hoisting mechanism is connected to the main frame mechanism 0100 for hoisting, and the glass tube row clamping mechanism is hoisted and stopped at the docking station of the glass tube row 0400. The clamping drive mechanism 0200 drives the clamping mechanism 0300 to open to both sides. After a row of glass tube rows 0400 conveyed from the front end arrives in place, the clamping drive mechanism 0200 drives the clamping mechanism 0300 to clamp towards the middle. At this time, the lower support plate 0307 extends out to support the entire row of tubes. After the hoisting mechanism hoists the clamping and conveying mechanism and moves backward to the designated position, the lower support plate 0307 retracts. The clamping drive mechanism 0200 drives the clamping mechanism 0300 to open to both sides, and places the entire row of tubes at the designated bundling station. The lower support plate 0307 itself has a certain length and can place a row of glass tube products with slightly different lengths, enabling the glass tube packaging machine with this mechanism to realize the subsequent clamping, conveying, and packaging of the glass tube row without performing end-trimming processing.

[0024] In some other specific embodiments of the present invention, the rest is the same as the above embodiment, except that, as Figure 2 shown, the clamping drive mechanism 0200 includes a servo motor 0201, a coupling 0202, a transmission lead screw 0203, a transmission nut 0204, a motor mounting seat 0205, a nut mounting seat 0206, a slider 0207, and a slide rail 0208; the servo motor 0201 is fixed on the main frame 0100 through the motor mounting seat 0205. The servo motor 0201 drives the transmission lead screw 0203. There is a nut 0204 on the transmission lead screw 0203. The nut 0204 is fixed on the slide rail 0208 through the nut mounting seat 0206. The slider 0207 is fixed on the main frame 0100, and the slide rail 0208 is slidably arranged in the slider 0207. When the servo motor 0201 is started to drive the transmission lead screw 0203, it can drive the nut 0204 to move back and forth. The nut 0204 is fixed on the nut mounting seat 0206 and fixedly connected to the slide rail 0208. The slide rail 0208 moves back and forth along the slider 0207 driven by the nut 0204. In this way, the main clamping plate 0302 arranged on the slide rail 0208 can move towards the center for clamping or move to both sides to release the glass tube.

[0025] In some other specific embodiments of the present invention, the rest is the same as the above embodiment, except that, as Figure 3As shown in the figure, on both sides of the main clamping plate 0302, there are main clamping plate sliders 0301, which are slidably arranged on the slide rail 0208 through the main clamping plate sliders 0301. On the slide rail 0208 inside the main clamping plate 0302, there is a positioning block 0303 fixed. A tension spring 0304 is connected between the positioning block 0303 and the main clamping plate 0302, so that the main clamping plate 0302 is tightened towards the positioning block 0303. When clamping a glass tube, when the glass tube abuts against the clamping plate, if the servo motor 0201 drives the transmission lead screw 0203 to further clamp the clamping plate inward, at this time, the main clamping plate 0302 will slide outward along the slide rail 0208 with the main clamping plate slider 0301, while the tension spring 0304 pulls the main clamping plate 0302, so that the main clamping plate 0302 clamps the glass tube under the action of the tension spring 0304 but will not continue to move inward to damage the glass tube.

[0026] In some other specific embodiments of the present invention, the rest is the same as the above embodiment, the difference is that, as Figure 3 shown, on both sides of the lower part of the auxiliary clamping plate 0309, there are side baffles 0308. When the lower support plate 0307 extends out, it forms a bucket shape together with the lower support plate 0307 to prevent the clamped glass tube from rolling to both sides.

[0027] In some other specific embodiments of the present invention, the rest is the same as the above embodiment, the difference is that, as Figure 4 shown, on the back of the auxiliary clamping plate 0309, there are a pair of auxiliary clamping plate slide rails 0311, and on the main clamping plate 0302, there are corresponding auxiliary clamping plate sliders 0310 arranged. The auxiliary clamping plate 0309 slides up and down in the auxiliary clamping plate sliders 0310 through the auxiliary clamping plate slide rails 0311; between the auxiliary clamping plate sliders 0310, there are an upper stop block 0312 and a lower stop block 0314, and between the auxiliary clamping plate slide rails 0311, there is a limit block 0313, and the limit block 0313 moves between the upper stop block 0312 and the lower stop block 0314 to limit the movement range of the auxiliary clamping plate 0309. When the bottom of the lower support plate 0307 touches the glass tube, it can slide up along the auxiliary clamping plate slider 0310 without crushing the glass tube. A corresponding induction alarm device can also be configured. Once the lower support plate 0307 touches the glass tube, an alarm can be issued to stop the hoisting mechanism from continuing to move downward with the clamping mechanism.

[0028] In some other specific embodiments of the present invention, the rest is the same as the above embodiment, the difference is that, as Figure 1 shown, at the center top of the main frame mechanism 0100, there is a hoisting connection pipe 050, which is convenient for connecting with the hoisting mechanism for hoisting.

[0029] Certainly, the above embodiments are only used to illustrate the technical concept and features of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model. Any equivalent transformation or modification made according to the spirit and essence of the main technical solution of the present utility model should be covered within the protection scope of the present utility model.
