DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] The utility model provides a glass bottle parting line grinding and polishing device, such as Figure 1 and Figure 2 As shown, the frame 1 includes a grinding electric spindle 2, which belongs to the prior art. For example, you can refer to the Chinese invention patent publication number CN112658294B "Electric spindle structure and electric spindle", two rows of grinding electric spindles 2 are arranged opposite to each other, and the grinding electric spindles 2 are installed with grinding wheels 201 for grinding the mold line 991 of the bottle 99. In other words, there are two rows of grinding electric spindles 2 on the frame 1, and the output shafts of the left row of grinding electric spindles 2 are arranged on the right, while the output shafts of the right row of grinding electric spindles 2 are arranged on the left, so that the grinding wheels 201 on the left row of grinding electric spindles 2 and the grinding wheels 201 on the right row of grinding electric spindles 2 are arranged opposite to each other, and the axes of the output shafts of the grinding electric spindles 2 are extended in the left-right direction, and the output shafts of the two left and right corresponding grinding electric spindles 2 can be coaxially arranged. Figures 1 to 3 As shown, the glass bottle parting line grinding and polishing device of the present invention also includes a conveying component 4 for conveying the vertically lying bottles 99, such as Figure 3 and Figure 7 As shown, the conveying assembly 4 includes an upper conveying belt 41 for contacting the upper part of the bottle 99 and a lower conveying belt 42 for contacting the lower part of the bottle 99, and the conveying assembly 4 includes a conveying motor assembly 43, as shown in FIG. Figure 5 As shown, the conveying motor assembly 43 drives the upper conveying belt 41 and the lower conveying belt 42 to operate. Figure 7 As shown, a positioning groove 4101 for the bottle 99 to sink into is formed on the outer side of the upper conveyor belt 41, and the positioning groove 4101 is extended along the upper conveyor belt 41. In other words, the extension direction of the positioning groove 4101 is perpendicular to the cross-section of the upper conveyor belt 41, so that the positioning groove 4101 extends in a full circle on the outer side of the upper conveyor belt 41.

[0023] The following briefly describes the working principle of the glass bottle parting line grinding and polishing device of the utility model: Figures 1 to 3 As shown, bottle 99 along Figure 2 The bottle 99 is fed between the upper conveyor belt 41 and the lower conveyor belt 42 in the direction indicated by the arrow in the figure. Since the upper conveyor belt 41 and the lower conveyor belt 42 are both made of rubber, the upper conveyor belt 41 and the lower conveyor belt 42 have a certain elasticity, so the upper conveyor belt 41 and the lower conveyor belt 42 can contact the bottle 99 at the same time to prevent the bottle 99 from being crushed. The upper conveyor belt 41 and the lower conveyor belt 42 drive the bottle 99 to be transported in a straight line through friction. During this period, as shown in FIG. Figure 7 As shown, the bottle 99 is in a vertically lying state. If the bottle 99 has a rotating body shape, then the central axis of the bottle 99 is along the conveying direction of the bottle 99, and the parting line 991 of the bottle 99 is located on the left and right sides of the bottle 99. The operation of each grinding electric spindle 2 drives the corresponding grinding wheel 201 to rotate. When the bottle 99 passes through the grinding wheel 201, the end face of the grinding wheel 201 can grind the corresponding parting line 991. After a series of grinding, the bottle 99 is moved away from the glass bottle parting line grinding and polishing device of the present invention by the conveying component 4. Since the two rows of grinding electric spindles 2 are arranged opposite to each other on the left and right, the parting lines 991 on the left and right sides of the bottle 99 can be polished by the corresponding grinding wheel 201. Since the output shafts of the left and right corresponding grinding electric spindles 2 are coaxially arranged, when the bottle 99 passes between the left and right grinding wheels 201, it is prevented from being subjected to non-parallel forces on the bottle 99. Figure 7 As shown, due to the positioning groove 4101, the upper part of the bottle 99 partially sinks upward into the positioning groove 4101, preventing the bottle 99 from being separated from the upper conveyor belt 41 to the left or right during the conveying process, which is conducive to the normal progress of the grinding process. In practical applications, in the conveying direction of the bottle 99, the abrasive grains of the grinding wheel 201 are gradually reduced, that is, coarse grinding is performed first, then fine grinding, and then fine grinding. The grinding wheel 201 at the end can also be a polishing grinding wheel, that is, the polishing grinding wheel is a special case of the grinding wheel 201, so the bottle 99 can achieve the effect from coarse grinding to polishing in one conveying process. As can be seen from the above, the glass bottle parting line grinding and polishing device of the utility model can realize mechanized grinding of the parting line, which is conducive to improving work efficiency and reducing labor intensity. The glass bottle parting line grinding and polishing device of the utility model can also be used for grinding and polishing ceramic bottles or plastic bottles.

[0024] Furthermore, if Figures 1 to 3As shown, a grinding wheel positioning assembly 3 is provided on the frame 1, and the grinding wheel positioning assembly 3 is provided with a slide seat 31, a positioning screw rod 32 and a positioning hand wheel 33. The slide seat 31 is slidably arranged in the left and right directions, that is, the sliding direction of the slide seat 31 is parallel to the axis of the output shaft of the grinding electric spindle 2. Specifically, the grinding wheel positioning assembly 3 is also provided with a base, the base is installed on the frame 1, the base and the slide seat 31 are slidably connected through a dovetail groove structure, the positioning screw rod 32 is rotatably arranged, the positioning screw rod 32 is connected to the above-mentioned base through a corresponding thrust ball bearing, the positioning screw 32 is screwed to the slide seat 31, specifically, a nut block is installed at the bottom of the slide seat 31, the positioning screw 32 is screwed to the above-mentioned nut block, and the positioning hand wheel 33 is installed at the end of the positioning screw rod 32, specifically, the positioning hand wheel 33 is installed at the end of the positioning screw rod 32 that is relatively far away from the corresponding grinding wheel 201; as shown Figure 1 and Figure 2 As shown, the grinding electric spindles 2 are respectively installed on the corresponding slides 31; therefore, when the adjustment hand wheel 33 is rotated, the adjustment hand wheel 33 drives the adjustment screw 32 to rotate synchronously, and the adjustment screw 32 can drive the slide 31 to move left and right to adjust the position, so that the end face of the grinding wheel 201 can be adjusted to the position adapted to the bottle 99, that is, the end face of the grinding wheel 201 can be close to the outer wall of the body of the bottle 99, so that each grinding electric spindle 2 can be adjusted separately. For example, the end face of the grinding wheel 201 on the grinding electric spindle 2 corresponding to the process of rough grinding the bottle 99 should be relatively far away from the central axis of the bottle 99, and the end face of the grinding wheel 201 on the grinding electric spindle 2 corresponding to the process of fine grinding the bottle 99 should be relatively close to the central axis of the bottle 99. When the outer diameter specification of the bottle 99 changes, the position of each grinding wheel 201 in the left and right direction can be adjusted accordingly through the grinding wheel adjustment assembly 3.

[0025] Furthermore, if Figure 5 As shown, the conveying assembly 4 includes an upper bracket 410, and the upper conveyor belt 41 is arranged on the upper bracket 410. The conveying assembly 4 includes an upper conveyor belt lifting mechanism 47, and the upper conveyor belt lifting mechanism 47 is connected to the upper bracket 410. In other words, the upper conveyor belt lifting mechanism 47 can drive the upper conveyor belt 41 to move up and down and adjust its position, so as to facilitate adjusting the upper conveyor belt 41 to a height position suitable for the outer diameter specification of the bottle 99.

[0026] Furthermore, if Figure 5 As shown, the upper conveyor belt lifting mechanism 47 includes a spiral lifter 471, a linkage shaft 472 and a worm gear reducer 473. Figure 6As shown, the spiral lifter 471 includes a column 4711, a lifting sleeve 4712 and a lifting screw 4713. The lower end of the column 4711 is installed and connected to the frame 1, and the lifting sleeve 4712 is slidably connected to the column 4711 up and down, specifically, the lifting sleeve 4712 is sleeved outside the column 4711, and the lifting screw 4713 is rotatably connected to the lifting sleeve 4712, that is, the lifting screw 4713 and the lifting sleeve 4712 are relatively positioned in the up and down directions, and the lifting screw 4713 is screwed to the column 4711, specifically, the lifting screw 4713 and the upper part of the column 4711 are coaxially arranged, as shown in FIG. Figure 5 As shown, two spiral lifters 471 are distributed, and the two ends of the upper bracket 410 are respectively installed and connected to the lifting sleeve 4712, and the worm gear reducer 473 is respectively installed on the upper end of the corresponding lifting sleeve 4712, and the output end of the worm gear reducer 473 is respectively connected to the upper end of the corresponding lifting screw 4713. Specifically, the output end of the worm gear reducer 473 is a hollow shaft, such as Figure 6 As shown, the upper end of the lifting screw 4713 is inserted into the corresponding hollow shaft mentioned above and connected by a flat key, and the two ends of the linkage shaft 472 are respectively connected to the input end of the corresponding worm gear reducer 473, that is, the worm of the worm gear reducer 473 is coaxially connected to the linkage shaft 472, so when the linkage shaft 472 is rotated, the two ends of the linkage shaft 472 respectively drive the corresponding worm gear reducer 473 to operate, so that the lifting screws 4713 of the two spiral lifters 471 can rotate synchronously, so that the two ends of the upper bracket 410 can be lifted and lowered synchronously, which is conducive to the force balance of the upper bracket 410. A lifting and lowering adjustment hand wheel can be set to be coaxially connected with the linkage shaft 472 (it should be noted that the above-mentioned lifting and lowering adjustment hand wheel is not drawn in each figure).

[0027] Furthermore, if Figure 5 As shown, the conveying assembly 4 includes an upper driving wheel 411 and a lower driving wheel 421. One end of the upper conveyor belt 41 is wound around the upper driving wheel 411, and one end of the lower conveyor belt 42 is wound around the lower driving wheel 421. The upper driving wheel 411 is rotatably arranged on the upper bracket 410. The upper bracket 410 is also rotatably connected to an upper supporting wheel 412. The other corresponding end of the upper conveyor belt 41 is wound around the upper supporting wheel 412. Thus, the upper driving wheel 411 and the upper supporting wheel 412 are combined to tension the upper conveyor belt 41. The middle part of the upper conveyor belt 41 is supported by the upper end of the upper bracket 410. Similarly, a lower supporting wheel 422 is rotatably arranged on the frame 1, and the other corresponding end of the lower conveyor belt 42 is wound around the lower supporting wheel 422. Figure 5As shown, the conveying assembly 4 includes a lower gear 44, an upper gear 45 and a telescopic universal joint 46, the conveying motor assembly 43 drives the lower gear 44 to rotate on a fixed axis, the upper gear 45 is meshed and connected to the lower gear 44, one end of the telescopic universal joint 46 is connected to the upper gear 45, and the other end of the telescopic universal joint 46 is connected to the upper drive wheel 411, and the lower drive wheel 421 is coaxially connected to the lower gear 44, the upper gear 45 and the lower gear 44 are arranged with the same number of teeth, and the lower gear 44 is arranged to rotate on a fixed axis; specifically, the conveying motor assembly 43 drives the lower gear 44 through the reducer assembly, and the output end of the above-mentioned reducer assembly is equipped with a transmission support shaft, and the axis of the above-mentioned transmission support shaft extends in the left and right directions, the lower drive wheel 421 is installed at one end of the above-mentioned transmission support shaft, and the lower gear 44 is installed at the other end corresponding to the above-mentioned transmission support shaft, so that the lower drive wheel 421 and the lower gear 44 are coaxial and rotate synchronously, and the output shaft of the conveying motor assembly 43 is connected to the input end of the above-mentioned reducer assembly, so The conveying motor assembly 43 drives the lower driving wheel 421 to rotate, and the lower gear 44 drives the upper gear 45 to rotate synchronously in the opposite direction, so that the upper driving wheel 411 and the lower driving wheel 421 rotate in the opposite direction, so that the upper driving wheel 411 drives the upper conveyor belt 41 to operate, and the lower driving wheel 421 drives the lower conveyor belt 42 to operate. Since the lower part of the upper conveyor belt 41 contacts the upper part of the bottle 99, and the upper part of the lower conveyor belt 42 contacts the lower part of the bottle 99, the direction of the friction force of the upper conveyor belt 41 on the bottle 99 is the same as the direction of the friction force of the lower conveyor belt 42 on the bottle 99; when the upper conveyor belt 41 is adjusted up and down by the upper conveyor belt lifting mechanism 47, since the upper gear 45 is connected to the upper driving wheel 411 by the telescopic universal joint 46, the axis of the upper gear 45 and the axis of the upper driving wheel 411 can be displaced by a certain amplitude.

[0028] Furthermore, if Figures 1 to 3 As shown, the frame 1 is provided with a water retaining side cover 5, and the two water retaining side covers 5 are symmetrically arranged on the left and right sides. The grinding wheel 201 is arranged in the area surrounded by the left and right water retaining side covers 5, as shown in FIG. Figure 4As shown, the water retaining side cover 5 is formed with an avoidance hole 501, and the avoidance hole 501 is connected to a water unloading cone tube portion 51, which is arranged on the inner side of the water retaining side cover 5, and the grinding electric spindle 2 is arranged through the corresponding water unloading cone tube portion 51, and the outer diameter of one end of the water unloading cone tube portion 51 connected to the avoidance hole 501 is smaller than the outer diameter of the end of the water unloading cone tube portion 51 relatively far away from the avoidance hole 501, that is, the end of the water unloading cone tube portion 51 with a relatively smaller outer diameter is welded to the edge of the avoidance hole 501, so that the outer wall of the water unloading cone tube portion 51 forms an acute angle with the side inner wall of the water retaining side cover 5, thereby forming an annular water groove between the outer wall of the water unloading cone tube portion 51 and the side inner wall of the water retaining side cover 5. When grinding the mold line 991, it is necessary to spray water on the bottle 991. The grinding wheel 201 rotates at a high speed to splash water onto the inner wall of the water retaining side cover 5. The water droplets flow down along the water retaining side cover 5. Since the above-mentioned annular water groove intercepts the water droplets flowing down from the inner wall of the water retaining side cover 5, the water droplets flow down along the above-mentioned annular water groove, thereby greatly reducing the water droplets sprayed on the grinding electric spindle 2.

[0029] Furthermore, if Figure 7 As shown, the positioning groove 4101 is set as a V-shaped groove, that is, the cross-section of the positioning groove 4101 includes two sides, and the above-mentioned two sides form an obtuse angle. Therefore, when the bottle 99 is against the positioning groove 4101, the positioning groove 4101 plays a left-right centering role for the bottle 99, that is, when the outer wall of the bottle 99 is against the above-mentioned two sides at the same time, the central axis of the bottle 99 is always located on the angle bisector of the above-mentioned obtuse angle, and the V-shaped groove can adapt to the change of the outer diameter specification of the bottle 99.

[0030] like Figure 1 As shown, the glass bottle parting line grinding and polishing device of the present invention further includes a water receiving tray 6 , which is located below the grinding wheel 201 and the lower conveyor belt 42 .

[0031] like Figure 1 and Figure 2 As shown, the glass bottle parting line grinding and polishing device of the present invention also includes a guide wheel assembly 7, which includes two rows of left and right guide wheels, and the conveying assembly 4 outputs the bottle 99 to between the left and right rows of guide wheels.
