[0002] In the production and manufacturing process of controlled glass bottles, it is necessary to cut the glass pipe fittings after the mouth of the bottle is shaped and cut into the required length of the controlled glass bottles. However, when the existing cutting device cuts the glass pipe fittings, the lengths of the glass bottles are usually inconsistent. Therefore, the workload of subsequent screening of the glass bottles is increased, which is not conducive to improving the production efficiency of the controlled glass bottles. Summary of the Utility Model

[0003] In view of this, the utility model aims to provide a cutting device for controlled glass bottles to improve the production efficiency of the controlled glass bottles.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] A cutting device for controlled glass bottles includes a base, a first turntable rotatably arranged on the base, a plurality of clamping assemblies rotatably arranged on the first turntable, and a positioning mechanism, a preheating station and a cutting station are sequentially arranged on the base. The first turntable drives a glass tube to move at the positioning mechanism, the preheating station and the cutting station in sequence through one of the clamping assemblies.

[0006] Each of the clamping assemblies includes a rotating body rotatably arranged on the first turntable, a mechanical claw assembly slidably arranged on the rotating body for clamping the glass tube, and a control member slidably arranged up and down on the rotating body, and the control member is used to control the sliding of the mechanical claw assembly.

[0007] The positioning mechanism includes a pushing member correspondingly arranged below the control member, a supporting seat correspondingly arranged below the glass tube, and a probe arranged on the pushing member. After the probe detects the glass tube, the supporting seat rises, and the pushing member rises to push the control member, so that the mechanical claw assembly releases the clamping of the glass tube. After the glass tube descends to contact the supporting seat, the supporting seat supports the glass tube to descend to a preset height, so as to achieve the purpose of limiting the required length of the glass bottle cut from the glass tube.

[0008] Furthermore, each of the mechanical claw assemblies includes a plurality of claw hands slidably disposed at the bottom of the rotating body along the radial direction of the rotating body, a connecting rod extending in the height direction on each of the claw hands, and an elastic member disposed on each of the connecting rods. Two ends of each elastic member respectively abut against the rotating body and the corresponding connecting rod, and each elastic member is configured to push against the corresponding connecting rod to move the corresponding claw hand away from the glass tube.

[0009] Furthermore, each of the connecting rods is in an "L" shape and has a long rod extending in the height direction and a short rod connected to the long rod. The short rod extends along the radial direction of the rotating body. When each of the connecting rods is subjected to the extrusion of the control member, it can cause each claw hand to push the corresponding long rod to slide along the radial direction of the rotating body through the corresponding short rod, and drive the corresponding claw hand to slide along the radial direction of the rotating body.

[0010] Furthermore, sliding grooves corresponding to each of the connecting rods are formed on the rotating body. Each of the connecting rods slides in the corresponding sliding groove, and the elastic member abuts between each short rod and the bottom of the sliding groove.

[0011] Furthermore, each of the control members includes a sliding table slidably disposed on the rotating body, a blocking member disposed on the top of the sliding table for restricting the short rod from sliding out, and a groove formed on the sliding table. The groove can enable each short rod to slide out to release the locking of each claw hand.

[0012] Furthermore, a guiding member extending in the height direction is disposed on each of the sliding tables. A strip-shaped hole extending in the height direction is formed in the guiding member. Guiding columns corresponding to each of the strip-shaped holes are disposed on the first rotating table. The guiding columns all extend along the radial direction of the rotating body, and the sliding table is slidably disposed on the guiding columns through the strip-shaped holes.

[0013] Furthermore, a protrusion is disposed at the bottom of the sliding table, and the protrusion is configured to receive the pushing of the pushing member.

[0014] Furthermore, a second rotating table is disposed below the cutting station. The second rotating table is rotatably disposed on the base, and a plurality of transfer assemblies arranged in the circumferential direction are disposed on the second rotating table. Each of the transfer assemblies is configured to clamp the glass tube cut from the cutting station.

[0015] Furthermore, each of the transfer assemblies includes a fixture for clamping the glass tube and a telescopic member disposed at the bottom of the fixture. The telescopic member is configured to drive the fixture to move up and down.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0018] Secondly, through the cooperation between the connecting rod and the elastic member, the claw hands can move radially away from the glass tube, thereby releasing the locking of the glass tube and allowing the glass tube to descend. Moreover, its structure is simple and convenient for design and implementation. The connecting rod is set as an L shape, and by setting a long rod and a short rod, the long rod is connected between the corresponding claw hand and the corresponding short rod to form a linkage between the connecting rod and the claw hand, so that the control member can make the claw hand slide radially along the rotating body and away from the glass tube by squeezing the short rod and through the connection between the long rods, realizing the unlocking of the glass tube and facilitating the descent of the glass tube.

[0019] Furthermore, by setting a sliding groove, the connecting rod slides in the sliding groove, which is convenient for realizing the stable sliding of the connecting rod. The elastic member is arranged between the short rod and the bottom of the sliding groove. With this setting, the structure is reasonable and the locking of the glass tube can be released under the action of the elastic member. By setting a blocking member and a groove, it is beneficial to limit the short rod and facilitate the switching between the two states of locking and unlocking the glass tube. The structure is relatively simple and convenient for its design and preparation.

[0020] In addition, through the cooperation between the sliding table and the strip-shaped hole and the guiding column, the sliding table can be guided and slid on the rotating body, which is convenient for ensuring the stable sliding of the sliding table. A convex portion for receiving the pushing of the pushing member is arranged at the bottom of the sliding table, which is convenient for the pushing member to push the sliding table.

[0041] Embodiment 1

[0042] This embodiment relates to a controlled glass bottle cutting device, which can limit the required length of the glass bottles cut from the glass tube 4 to improve the production efficiency of the controlled glass bottles.

[0043] In terms of the overall structure, as shown in Figures 1 to 9 , the controlled glass bottle cutting device of this embodiment includes a base 1, a first turntable 2 rotatably arranged on the base 1, and a plurality of clamping components 21 rotatably arranged on the first turntable 2. And a positioning mechanism 11, a preheating station 12, and a cutting station 13 are sequentially arranged on the base 1. The first turntable 2 drives the glass tube 4 to move sequentially at the positioning mechanism 11, the preheating station 12, and the cutting station 13 through one of its clamping components 21.

[0044] Among them, each clamping assembly 21 includes a rotating body 210 rotatably arranged on the first turntable 2, a mechanical claw assembly 212 slidably arranged on the rotating body 210 for clamping the glass tube 4, and a control member 213 slidably arranged up and down on the rotating body 210, and the control member 213 is used to control the sliding of the mechanical claw assembly 212.

[0045] And the positioning mechanism 11 includes a pushing member 111 correspondingly arranged below the control member 213, a supporting seat 112 correspondingly arranged below the glass tube 4, and a probe 113 arranged on the pushing member 111. After the probe 113 detects the glass tube 4, the supporting seat 112 rises upward, and the pushing member 111 rises upward to push the control member 213, so that the mechanical claw assembly 212 releases the clamping of the glass tube 4. After the glass tube 4 descends to contact the supporting seat 112, the supporting seat 112 supports the glass tube 4 to descend to a preset height, so as to achieve the purpose of limiting the required length of the glass tube 4.

[0046] At this time, as set above, by setting the pushing member 111, the supporting seat 112 in the positioning mechanism 11 and the control member 213, the mechanical claw assembly 212 in the clamping assembly 21, not only can the control member 213 be used to control the mechanical claw assembly 212 to realize the clamping of the glass tube 4 and ensure the stable placement of the glass tube 4, but also the cooperation between the control member 213 and the pushing member 111, the supporting seat 112 can be used to limit the required length of the glass bottle cut from the glass tube 4, avoiding the tediousness of subsequent screening of the glass bottles, and helping to improve the production efficiency of the controlled glass bottles.

[0047] In this embodiment, by setting the preheating station 12 to preheat the glass tube 4 to be cut, the temperature difference of each part at the cutting position can be reduced, and the cutting accuracy can be improved. And both the preheating station 12 and the cutting station 13 in this embodiment achieve the purposes of preheating and cutting by spraying flames. Of course, in addition to the flame cutting method, the cutting station 13 can also adopt other common cutting methods.

[0048] It should be noted that for the above-mentioned preset height, it refers to the required length of the glass bottle cut from the glass tube 4. The required length of the glass bottle can be input into the control system of the device, so as to control the descending height of the supporting seat 112 to achieve the purpose of unifying the required length of the glass bottle.

[0049] In addition, the pushing member 111 in this embodiment can adopt driving products well-known to those skilled in the art, such as electric push rods, etc., as long as it can achieve the purpose of pushing space.

[0050] During specific implementation, such as Figure 2 and Figure 4As shown, after the probe 113 detects the presence of the glass tube 4, the supporting seat 112 rises upward. At this time, the pushing member 111 rises upward to push against the control member 213, so as to release the control of the control member 213 on the mechanical claw assembly 212, and further release the locking of the glass tube 4, so that the glass tube 4 descends to release the supporting seat 112, and under the supporting action of the supporting seat 112, the supporting seat 112 drives the glass tube 4 to descend to a preset height. Thus, the purpose of limiting the length of the glass tube 4 can be achieved, so as to facilitate the subsequent cutting and unify the length of the glass bottles.

[0051] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 7 shown, each mechanical claw assembly 212 includes a plurality of claw hands 2121 slidably arranged at the bottom of the rotating body 210 along the radial direction of the rotating body 210, a connecting rod 2122 extending in the height direction on each claw hand 2121, and an elastic member 2123 arranged on each connecting rod 2122. The two ends of each elastic member 2123 respectively abut against the rotating body 210 and the corresponding connecting rod 2122, and each elastic member 2123 is used to push against the corresponding connecting rod 2122 to make the corresponding claw hand 2121 away from the glass tube 4.

[0052] Here, through the cooperation between the claw hand 2121, the connecting rod 2122 and the elastic member 2123, each claw hand 2121 can be made to move radially away from the glass tube 4, so as to release the locking of the glass tube 4 and make the glass tube 4 descend. Moreover, its structure is simple and it is also convenient for design and implementation. And, the elastic member 2123 in this embodiment can be a spring well-known to those skilled in the art.

[0053] It is worth mentioning that the number of claw hands 2121 can be set to four. Of course, in addition to being set to four, the number of claw hands 2121 can also be set to five or six according to the actual clamping requirements of the glass tube 4, as long as it can meet the clamping of the glass tube 4.

[0054] In the specific structure, when the probe 113 does not detect the glass tube 4, the control member 213 always squeezes the connecting rod 2122 to make each claw hand 2121 close to the glass tube 4, so as to achieve the purpose of clamping the glass tube 4. After the probe 113 detects the glass tube 4, the pushing member 111 rises upward to push the control member 213 so that the control member 213 releases the control of the connecting rod 2122. At this time, under the action of the elastic member 2123, the connecting rod 2122 is pushed to slide out of the rotating body 210, so as to release the clamping of each claw hand 2121 on the glass tube 4.

[0055] Specifically, in this embodiment, as a preferred implementation form, referring to Figure 7 and Figure 8As shown in the figure, each connecting rod 2122 is in an "L" shape and has a long rod 21222 extending in the height direction and a short rod 21221 connected to the long rod 21222. The short rod 21221 extends radially along the rotating body 210. When each connecting rod 2122 is subjected to the extrusion of the control member 213, it can cause each gripper 2121 to push the corresponding long rod 21222 to slide radially along the rotating body 210 through the corresponding short rod 21221, and drive the corresponding gripper 2121 to slide radially along the rotating body 210.

[0056] The advantage of such a setting is that the connecting rod 2122 is set in an "L" shape, and by setting the long rod 21222 and the short rod 21221, the long rod 21222 is connected between the corresponding gripper 2121 and the corresponding short rod 21221 to form a linkage between the connecting rod 2122 and the gripper 2121. The control member 213 can cause the gripper 2121 to slide radially along the rotating body 210 and away from the glass tube 4 by extruding the short rod 21221 and through the connection between the long rods 21222, so as to unlock the glass tube 4 and facilitate the descent of the glass tube 4.

[0057] In the specific structure, still referring to Figure 7 As shown in the figure, the end of the short rod 21221 away from the long rod 21222 can be set to a spherical shape to facilitate the sliding of the control member 213 and reduce the hard friction between the short rod 21221 and the control member 213. Of course, in addition to being set to a spherical shape, it can also be set to other shapes, such as an elliptical shape, a semi-circular shape, etc., as long as it can meet the requirement that the control member 213 slides conveniently.

[0058] Moreover, considering the sliding requirement of the connecting rod 2122, in this embodiment, as a preferred implementation form, referring to Figure 7 and Figure 8 As shown in the figure, the rotating body 210 is provided with sliding grooves 211 corresponding to each connecting rod 2122 one by one. Each connecting rod 2122 slides in the corresponding sliding groove 211, and the elastic member 2123 abuts between each short rod 21221 and the bottom 2111 of the sliding groove 211.

[0059] Here, by setting the sliding groove 211, the connecting rod 2122 slides in the sliding groove 211, which is convenient for realizing the stable sliding of the connecting rod 2122, and the elastic member 2123 is arranged between the short rod 21221 and the bottom 2111 of the sliding groove 211. With this setting, the structure is reasonable, and the glass tube 4 can be unlocked under the action of the elastic member 2123.

[0060] It is worth mentioning that in order to meet the sliding requirements of the connecting rod 2122, the sliding groove 211 is also set to be "L"-shaped, and has a long groove extending along the axial direction of the rotating body 210, and a short groove connected to the long groove. The short groove extends along the radial direction of the rotating body 210. Moreover, in the specific structure, a reserved space is also provided in the long groove, and the elastic member 2123 can be placed in the reserved space.

[0061] Of course, in addition to abutting the elastic member 2123 between the short rod 21221 and the bottom 2111 of the sliding groove 211, the elastic member 2123 can also be abutted between the bottom 2111 of the sliding groove 211 and the long rod 21222. It should be noted that the bottom 2111 of the sliding groove 211 in this embodiment is the side wall of the long groove facing the short rod 21221.

[0062] In addition, in this embodiment, as a preferred implementation form, referring to Figure 5 and Figure 6 as shown, each control member 213 includes a sliding table 2131 slidably disposed on the rotating body 210 in the up and down direction, a blocking member 2132 disposed on the top of the sliding table 2131 for restricting the short rod 21221 from sliding out, and a groove 2133 formed in the sliding table 2131. The groove 2133 can enable each short rod 21221 to slide out to release the locking of each gripper 2121. Here, by providing the blocking member 2132 and the groove 2133, it is beneficial to realize the restriction of the short rod 21221, and it is convenient to realize the switching between the two states of locking and unlocking the glass tube 4, and the structure is relatively simple, which is convenient for its design and preparation.

[0063] In the specific structure, referring to Figure 6 and Figure 7 as shown, the blocking member 2132 is set to be annular. When the probe 113 does not detect the glass tube 4, the control member 213 squeezes each short rod 21221 through the blocking member 2132, thereby driving the corresponding long rod 21222 and the corresponding gripper 2121 to slide along the radial direction of the rotating body 210 and close to the glass tube 4 to realize the clamping of the glass tube 4. When the probe 113 detects the glass tube 4, the pushing member 111 pushes the control member 213 to slide upward, so that the blocking member 2132 releases the extrusion of the short rod 21221.

[0064] Moreover, the existence of the groove 2133 can form a sliding space for the short rod 21221. Under the tendency of the elastic member 2123, each short rod 21221 slides along the radial direction of the rotating body 210 away from the glass tube 4, thereby driving the corresponding long rod 21222 and the corresponding gripper 2121 to slide and releasing the clamping of the glass tube 4.

[0065] At the same time, in this embodiment, as a preferred implementation form, referring to Figure 2 、 Figure 5 and Figure 6As shown, a guide member 21311 extending in the height direction is provided on each sliding table 2131. A strip-shaped hole 21312 extending in the height direction is formed in the guide member 21311. Guide columns 22 corresponding to the strip-shaped holes 21312 are provided on the first turntable 2. The guide columns 22 all extend radially along the rotating body 210, and the sliding table 2131 is slidably arranged on the guide columns 22 through the strip-shaped holes 21312.

[0066] Here, through the cooperation of the strip-shaped hole 21312 and the guide column 22, the sliding table 2131 can achieve guiding and sliding on the rotating body 210, which is convenient for ensuring the stable sliding of the sliding table 2131. Of course, the shape of the strip-shaped hole 21312 in this embodiment can be set to other common shapes in addition to the current long strip shape, as long as it can satisfy the stable sliding of the sliding table 2131 on the guide column 22.

[0067] Moreover, in order to facilitate the sliding table 2131 to receive the pushing force of the pushing member 111, in this embodiment, as a preferred implementation form, as Figure 3 、 Figure 4 and Figure 6 shown, a protrusion 21313 is provided at the bottom of the sliding table 2131, and the protrusion 21313 is used to receive the pushing of the pushing member 111. Setting a protrusion 21313 for receiving the pushing of the pushing member 111 at the bottom of the sliding table 2131 can facilitate the pushing member 111 to push the sliding table 2131.

[0068] In the specific structure, referring to Figure 6 shown, the sliding table 2131 can be set as a large circular plate and a small circular plate spliced together. The small circular plate is correspondingly arranged above the pushing member 111, and the protrusion 21313 is arranged on the small circular plate, which is convenient for the pushing member 111 to push.

[0069] In addition, in this embodiment, as a preferred implementation form, as Figure 1 and Figure 9 shown, a second turntable 3 is provided below the cutting station 13. The second turntable 3 is rotatably arranged on the base 1, and a plurality of transfer components 31 arranged along the circumferential direction are provided on the second turntable 3. Each transfer component 31 is used to clamp the glass bottles cut from the cutting station 13. By providing a plurality of transfer components 31 on the second turntable 3, it is convenient to transfer the glass tubes 4 cut from the cutting part to the next process.

[0070] Here, it is worth mentioning that the number of the transfer components 31 in this embodiment can be arranged correspondingly according to the number of the clamping components 21 described above. For example, if the clamping components 21 are set to eight, that is, the transfer components 31 are correspondingly set to eight.

[0071] And, in this embodiment, as a preferred implementation form, asFigure 9 As shown in the figure, each transfer component 31 includes a fixture 311 for clamping the glass tube 4 and a telescopic member 312 provided at the bottom of the fixture 311. The telescopic member 312 is used to drive the fixture 311 to lift and lower. Here, by providing the telescopic member 312, it is convenient for the fixture 311 to lift and lower to clamp the glass tube 4 cut from the cutting station 13. Moreover, the telescopic member 312 in this embodiment can adopt products well-known to those skilled in the art, such as electric push rods and the like.

[0072] During specific implementation, one clamping component 21 drives the glass tube 4 to move to the cutting station 13 for cutting. At this time, the fixture 311 at the cutting station 13 rises under the drive of the telescopic member 312 to clamp the middle part of the cut glass tube 4. The glass tube 4 is cut by flame at the cutting station 13. Then, under the drive of the telescopic member 312, the fixture 311 clamps the cut glass bottle and descends, and is transferred under the rotation of the second turntable 3.

[0073] When the glass tube cutting device of this embodiment is in use, first, the glass tube 4 is inserted into the clamping component 21 and moves under the rotation of the first turntable 2. When it moves to the positioning mechanism 11, the probe 113 detects the presence of the glass tube 4, and the supporting seat 112 rises upward. Then, the pushing member 111 pushes the protrusion 21313 to make the sliding table 2131 slide upward.

[0074] At this time, each short rod 21221 breaks away from the restriction of the blocking member 2132, slides out of the rotating body 210 along the radial direction of the rotating body 210, and drives the corresponding long rod 21222 and the corresponding claw 2121 to slide, so as to release the clamping effect of each claw 2121 on the glass tube 4, and the glass tube 4 descends to contact the supporting seat 112. Subsequently, after the supporting seat 112 supports the glass tube 4 and descends to a preset height, it is transferred to the preheating station 12 for preheating through the first turntable 2.

[0075] Secondly, after preheating is completed, it is transferred to the cutting station 13 again through the first turntable 2 to perform flame cutting on the glass tube 4. At this time, the fixture 311 rises under the drive of the telescopic member 312 to clamp the middle part of the cut glass bottle. Then the fixture 311 clamps the glass bottle and descends, and is transferred under the action of the second turntable 3.

[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
