Description

Technical Field

[0001] The utility model relates to the field of glass tube production and preparation, in particular to a large glass tube combing device. Background Art

[0002] In the existing borosilicate glass tube production line, a combing device is required to transport the glass tube. Common combing devices usually use Figure 1 The T-shaped limit column shown in the figure limits the glass tube. In the prior art, the contact area between the limit column and the glass tube is relatively large. Since the entire production line cannot achieve a dust-free environment, and the existing limit columns are usually made of bakelite (i.e., a plastic product made of bakelite powder or bakelite powder mainly filled with wood powder), dust and other impurities are easily attached to the surface. Therefore, in the process of transporting the glass tube, the impurities on the limit column will cause chain marks between the glass tube and the limit column, which greatly affects the quality of the glass tube and reduces the yield rate of the glass tube.

[0003] For example, the utility model patent with the authorization announcement number CN219602624U provides a glass tube combing device, and the glass tube combing device of this scheme includes: a first combing device, a second combing device and a bridging device, wherein the first combing device includes: a first transmission rack and a plurality of first limiting posts, two adjacent first limiting posts cooperate with the first transmission rack to form a first limiting recess, and the second combing device includes: a second transmission rack and a plurality of second limiting posts, two adjacent second limiting posts cooperate with the second transmission rack to form a second limiting recess. According to the description in the specification and in combination with the drawings, when the first limiting posts and the second limiting posts are in contact with the glass tube, their contact surfaces may have the above-mentioned problems. Based on this, the prior art still needs to be improved. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a large combing device for glass tubes, which can at least solve the technical problem that the existing column mechanism is prone to dust adhesion and affects the quality of the glass tubes.

[0005] The utility model provides a large combing device for glass tubes, comprising: two rows of column mechanisms arranged in parallel, each column mechanism comprising: a first support plate and a second support plate. The upper surface of the first support plate is the first support surface; the second support plate is vertically mounted on the upper surface of the first support plate, and the two surfaces of the second support plate and the first support plate forming an angle are the second support surfaces; each end of the glass tube is arranged between the second support plates of two adjacent column mechanisms and is located above the first support plate; wherein the first support surface is provided with a first support edge for contacting the glass tube, and the second support surface is provided with a second support edge for contacting the glass tube.

[0006] In some embodiments, the first supporting edge is perpendicular to the axis of the glass tube, the second supporting edge is vertically arranged, and the width of the first supporting edge and the second supporting edge is 1.5 mm to 3 mm, so that the first supporting edge and the second supporting edge can minimize the contact area with the glass tube while having a good supporting effect.

[0007] In some embodiments, the large glass tube combing device further comprises two transmission mechanisms, each of which comprises a conveyor chain and sprockets arranged at both ends of the conveyor chain to drive the conveyor chain to rotate; each row of column mechanisms is installed on the outer ring of a conveyor chain. The rotation of the conveyor chain drives the column mechanisms thereon to move, thereby driving the entire glass tube to move.

[0008] In some embodiments, each transmission mechanism also includes a chain tug, which is rotatably disposed below the conveyor chain and engages with the conveyor chain to avoid or reduce problems caused by slackness of an over-long conveyor chain; a positioning plate is installed on one side of each link of the conveyor chain, and each column mechanism is installed on a positioning plate to prevent the column mechanism from being interfered with by the chain tug when it moves downward with the conveyor chain.

[0009] In some embodiments, the two end faces of each second support plate in the length direction are inclined surfaces, and the inclined direction thereof is gradually approaching the middle of the second support plate from bottom to top, so as to avoid contact between the column mechanism and the chain pulley, thereby preventing oil stains from contaminating the glass.

[0010] In some embodiments, a mounting hole is provided on the positioning plate; a positioning hole is provided on the second support plate, and the second support plate is installed on the positioning plate by bolts passing through the positioning hole and the mounting hole, so the installation is convenient and quick.

[0011] In some embodiments, two clips are provided on the lower surface of the first support plate, and the clips are used to clip on both ends of the positioning plate to quickly locate the installation position of the column mechanism and prevent the column mechanism from shaking left and right when tightening the bolts and in long-term use.

[0012] In some embodiments, the positioning plate is disposed on the inner side of the conveyor chain to prevent the oil stains on the chain from scratching the glass tube.

[0013] In some embodiments, the inclination angle of the inclined surface of the second support plate is at least greater than the inclination angle from the middle of the surface of the chain tug to its edge tooth surface, ensuring that the column mechanism never contacts the chain tug when moving to the chain tug with the conveyor chain, avoiding oil stains.

[0014] In some embodiments, the first supporting edge and the second supporting edge are staggered to prevent the glass tube from being broken due to being subjected to large forces in one circle at the same time.

[0015] The beneficial effects of the utility model are as follows: by arranging narrower supporting edges on the first supporting surface and the second supporting surface, the utility model can reduce the probability of dust or broken glass slag falling on the contact surface, thereby reducing the range and probability of dust or broken glass slag affecting the surface of the glass tube, and improving the yield rate of the glass tube.

[0022] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to understand that multiple modifications are feasible without actually departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.

[0023] like Figure 2 and Figure 3As shown, a large combing device for glass tubes provided by an embodiment of the utility model comprises: two rows of column mechanisms arranged in parallel, and a column mechanism in each row comprises a first support plate 1 and a second support plate 2. The upper surface of the first support plate 1 is the first support surface. The second support plate 2 is vertically mounted on the upper surface of the first support plate 1. The two sides of the second support plate 2 and the first support plate 1 that form an angle are the second support surfaces. Each end of the glass tube 7 is arranged between the second support plates 2 of two adjacent column mechanisms and is located above the first support plate 1 to prevent multiple glass tubes 7 from gathering together. Among them, a first support ridge 3 for contacting the glass tube 7 is arranged on the first support surface, and a second support ridge 4 for contacting the glass tube 7 is arranged on the second support surface. In particular, the material of the column mechanism can also be replaced with Teflon material, so that the column mechanism has good high temperature resistance, corrosion resistance, non-stickiness and electrical insulation performance, etc., which is suitable for limiting the position of the glass tube 7, and can quickly and effectively clean the dust and oil stains falling on it, further reducing the impact on the quality of the glass tube 7.

[0024] Compared with the prior art, the utility model can reduce the probability of dust or broken glass falling on the contact surface by arranging narrower supporting edges on the first supporting surface and the second supporting surface, thereby reducing the range and probability of dust or broken glass affecting the surface of the glass tube 7, and improving the yield rate of the glass tube 7.

[0025] In some embodiments, the first supporting edge 3 is perpendicular to the axis of the glass tube 7, and the second supporting edge 4 is vertically arranged. The width of the first supporting edge 3 and the second supporting edge 4 is 1.5 mm to 3 mm, and can be set to 2 mm. The specific width can be selected according to the size of the glass tube 7, so that the first supporting edge 3 and the second supporting edge 4 can minimize the contact area with the glass tube 7 while having a better supporting effect.

[0026] In some embodiments, the large combing device for glass tubes further includes two transmission mechanisms (not shown in the figure), each of which includes a conveyor chain and sprockets arranged at both ends of the conveyor chain to drive the conveyor chain to rotate, and the rotation of the sprockets can be controlled by a motor. The column mechanism of each row is installed on the outer ring of a conveyor chain, and the rotation of the conveyor chain drives the column mechanism thereon to move, thereby driving the glass tube 7 to move as a whole. The conveyor chain can be used to transport multiple glass tubes 7 at one time, thereby improving work efficiency and avoiding the risks caused by manual handling, which helps to ensure the stable quality of the glass tube 7 during the production process.

[0027] In some embodiments, each transmission mechanism further includes a chain tug (not shown in the figure), which is rotatably disposed below the conveyor chain and meshes with the conveyor chain. In order to improve the carrying capacity of the transmission mechanism, the conveyor chain is usually designed to be longer. As the length of the conveyor chain increases, its own weight and the weight of the items it bears will also increase, which may cause the conveyor chain to vibrate or deviate during operation, affecting the conveying accuracy of the product. An overlong conveyor chain may become loose, that is, the conveyor chain gradually becomes longer due to the gravity. In order to prevent this from happening, the utility model arranges a chain tug below the conveyor chain to support the hanging conveyor chain upward, which can alleviate or avoid the above-mentioned problems. The conveyor chain is composed of a plurality of hinged links, a positioning plate is installed on one side of each link, and each column mechanism is installed on a positioning plate. Because after the chain tug is set under the conveyor chain, the chain tug needs to engage with the outer ring of the conveyor chain, the column mechanism cannot be set on the outer ring surface of the conveyor chain. In order to avoid the column mechanism being interfered by the chain tug when it moves downward with the conveyor chain, the column mechanism is installed on one side of the conveyor chain by installing a positioning plate to ensure the normal operation of the transmission mechanism.

[0028] In some embodiments, the length direction of the second support plate 2 is consistent with the axial direction of the glass tube 7, and the two end faces of each second support plate 2 in the length direction are inclined surfaces, and the inclined direction thereof is gradually approaching the middle of the second support plate 2 from bottom to top. Since the chain puller has a certain thickness, and in order to improve the wear resistance of the chain puller and reduce the friction of the sprocket tooth edge, the chain puller is usually designed to be thick in the middle and thin at the tooth edge. In order to be suitable for the chain puller of this structure, the utility model cuts the two side edges of the second support plate 2 and removes part of the material, which can avoid contact with the chain puller, thereby preventing oil stains from sticking to the column mechanism and contaminating the glass.

[0029] In some embodiments, the positioning plate is provided with a mounting hole; the second support plate 2 is provided with a positioning hole 6, and the second support plate 2 is mounted on the positioning plate by bolts passing through the positioning hole 6 and the mounting hole. Figure 2 As shown, the mounting hole is vertically arranged in the middle of the second support plate 2, and a limiting groove for placing the bolt cap is reserved on the top of the second support plate 2. This bolt mounting method makes assembly and disassembly more convenient and quick, thereby improving assembly efficiency.

[0030] In some embodiments, two clips 5 are provided on the lower surface of the first support plate 1, and the clips 5 are used to clip on both ends of the positioning plate to quickly locate the installation position of the column mechanism and prevent the column mechanism from shaking left and right when tightening the bolts and in long-term use.

[0031] In some embodiments, the positioning plate is disposed on the inner side of the conveyor chain so that the column mechanism is located on the inner side of the conveyor chain to prevent the oil stains on the conveyor chain from scratching the glass tube 7 .

[0032] In some embodiments, the inclination angle of the inclined surface of the second support plate 2 is at least greater than the inclination angle from the middle of the chain tug to its edge tooth surface, ensuring that the column mechanism never contacts the chain tug when moving to the chain tug with the conveyor chain, avoiding oil stains.

[0033] In some embodiments, the first supporting edge 3 and the second supporting edge 4 are staggered to prevent the glass tube 7 from being broken due to being subjected to large forces at the same time.

[0034] The above embodiments are possible examples of implementation methods of the utility model, and are only given to enable those skilled in the art to clearly understand the principles of the utility model.
