Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical glass bottle production technology, specifically to a clamping device and polishing equipment for pharmaceutical glass bottles. Background Technology

[0002] In the production of pharmaceutical glass bottles, processes such as cutting, firing, polishing, testing, sterilization, and packaging have a significant impact on product quality. Among these, the flatness of the bottle neck directly affects the sealing of the pharmaceutical packaging; therefore, bottle neck polishing is one of the key processes to ensure the performance of the glass bottle meets standards. Existing technologies, such as Chinese utility model patent CN202222695928.9, provide a glass bottle neck polishing device. This device, through its structure including an air pump, pneumatic telescopic column, rotating motor, and detachable polishing disc, improves the efficiency of polishing disc replacement and reduces maintenance costs. However, the device's fixed assembly of the fixing cylinder only accommodates glass bottles of specific sizes, resulting in poor equipment versatility and thus increasing production costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping device and a grinding equipment for pharmaceutical glass bottles, so as to solve the problem that the clamping device in the existing technology can only be adapted to glass bottles of specific specifications, resulting in poor equipment versatility and thus increasing production costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A clamping device for pharmaceutical glass vials, comprising:

[0006] First mounting base;

[0007] The second mounting base is spaced above the first mounting base to form a vertical moving channel, and the second mounting base has a clamping space.

[0008] Multiple clamping members are spaced apart and arranged around the clamping space. Each clamping member includes an adjusting block, a mounting block, and a clamping block disposed on the mounting block. The adjusting block is slidably connected to the first mounting base and the second mounting base and slides towards the clamping space. The mounting block is disposed at the upper end of the adjusting end and is located above the second mounting base. The clamping end of the clamping block faces the clamping space.

[0009] The drive block slides back and forth along the moving channel in the up and down direction. The circumferential surface of the drive block is provided with multiple connecting frames corresponding to the multiple clamping members with the central axis of the moving channel as the axis. The connecting frame includes a first connecting frame and a second connecting frame that are rotatably connected to each other. The first connecting frame is rotatably connected to the drive block, and the second connecting frame is fixedly connected to the adjusting block.

[0010] When the drive block slides up and down, the first connecting frame and the second connecting frame enable the multiple clamping members to have a clamping state and a releasing state. In the clamping state, the drive block moves upward, causing the multiple clamping members to synchronously retract inward toward the clamping space. In the releasing state, the drive block moves downward, causing the multiple clamping members to synchronously extend outward toward the clamping space.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. With multiple adjustable clamping components evenly distributed around the clamping space and the drive block sliding in one direction, the size of the clamping space can be flexibly adjusted, which can be adapted to pharmaceutical glass bottles of different specifications and diameters, significantly improving its versatility.

[0013] Furthermore, both the first mounting base and the second mounting base are provided with multiple sliding grooves, and each of the multiple sliding grooves corresponds to one of the multiple clamping members and slides in cooperation with each other.

[0014] Furthermore, the mounting block is provided with mounting holes, and the clamping block is provided with fixing holes. The mounting holes and fixing holes are connected to each other for fasteners to pass through and lock.

[0015] Furthermore, the first mounting base is rotatably provided with a lead screw via a mounting bracket. The lead screw is arranged in the vertical direction and threadedly connected to the drive block. The first mounting base is equipped with a motor, and the output end of the motor is connected to one end of the lead screw.

[0016] Furthermore, the first mounting base has a stepped surface.

[0017] Furthermore, the bottom of the second mounting base extends outward to form an outer flange, and the outer flange is provided with multiple bolt holes.

[0018] This utility model also provides a polishing device, including the above-mentioned clamping device for pharmaceutical glass bottles, a worktable, and a polishing mechanism disposed on the worktable for polishing the mouth of the pharmaceutical glass bottle, wherein the clamping device is disposed on the worktable.

[0019] Furthermore, the polishing mechanism includes a frame disposed on the worktable, a lifting assembly disposed on the frame, and a polishing assembly disposed on the lifting assembly. Attached Figure Description

[0035] Example 1

[0036] like Figure 1-3 As shown, this utility model embodiment proposes a clamping device for pharmaceutical glass bottles, including a first mounting base 10, a second mounting base 20, a plurality of clamping members 30, and a driving block 40; the second mounting base 20 is spaced above the first mounting base 10 to form a vertical moving channel, and the second mounting base 20 has a clamping space. To improve the stability of the second mounting base 20, it can be connected to the first mounting base 10 via a support frame; the plurality of clamping members 30 (three clamping members 30 are used as an example in this embodiment) are spaced around the clamping space. Each clamping member 30 includes an adjusting block 31, a mounting block 32, and a clamping block 33 disposed on the mounting block 32. The adjusting block 31 is slidably connected to the first mounting base 10 and the second mounting base 20 and slides towards the clamping space. The mounting block 32 is disposed at the upper end of the adjusting end and is located above the second mounting base 20. The clamping end of the clamping block 33 faces the clamping space; the driving block 40 slides back and forth along the moving channel in the vertical direction, and the circumferential surface of the driving block 40 is provided with a plurality of connecting frames 50 corresponding to the plurality of clamping members 30 with the central axis of the moving channel as the axis. The connecting frame 50 includes a first connecting frame 51 and a second connecting frame 52 that are rotatably connected to each other. The first connecting frame 51 is rotatably connected to the driving block 40, and the second connecting frame 52 is fixedly connected to the adjusting block 31. When the driving block 40 slides up and down, the plurality of clamping members 30 are in a clamping state and a releasing state through the first connecting frame 51 and the second connecting frame 52. In the clamping state, the driving block 40 moves upward, causing the plurality of clamping members 30 to simultaneously retract inward toward the clamping space; in the releasing state, the driving block 40 moves downward, causing the plurality of clamping members 30 to simultaneously extend outward toward the clamping space.

[0037] In this embodiment of the invention, in the initial state (released state), the drive block 40 is in a downward position, which drives the first connecting frame 51 and the second connecting frame 52 connected to it to extend the clamping block 33 of the clamping member 30 outward toward the clamping space, opening the clamping space to facilitate the placement of pharmaceutical glass bottles of different sizes. Next, the drive block 40 slides upward in the vertical direction, driving the adjusting block 31 to slide through the first connecting frame 51 and the second connecting frame 52, thereby driving the clamping block 33 of the clamping member 30 to simultaneously retract inward, clamping the pharmaceutical glass bottle located in the clamping space. Subsequently, the drive block 40 slides downward again, and the clamping member 30 simultaneously opens outward, quickly releasing the pharmaceutical glass bottle, thus completing the cycle of clamping and releasing actions in the polishing equipment. This eliminates the need for customized clamping devices for different sizes of glass bottles; one device can be used for multiple sizes, reducing the number of clamps and the costs of equipment purchase, management, and maintenance.

[0038] In this embodiment, the clamping block 33 can be made of a flexible material (such as silicone, rubber, or polyurethane) to prevent hard materials (such as metal) from directly contacting the glass bottle and causing scratches or breakage. Simultaneously, its surface in contact with the glass bottle can be designed with anti-slip textures (such as diamond patterns or grooves) to increase friction, prevent slippage during clamping, and further improve clamping stability. Furthermore, the clamping end of the clamping block 33 can be designed as an arc-shaped concave surface to fit snugly against the outer wall of the glass bottle, increasing the contact area and dispersing pressure. Of course, in another embodiment, the clamping block 33 can also be divided into a base and a replaceable pad. The base is fixed to the mounting block, while the pad is made of a flexible material and fixed by slots or screws to facilitate the replacement of worn parts.

[0039] Specifically, such as Figure 3 As shown in this embodiment of the invention, both the first mounting base 10 and the second mounting base 20 are provided with multiple sliding grooves 21. Each of the multiple sliding grooves 21 corresponds one-to-one with a multiple clamping member 30, and they slide in cooperation with each other. This allows the clamping member 30 to slide synchronously towards the clamping space along the direction of the sliding groove 21 under the drive of the drive block 40, ensuring coordinated and unified clamping and releasing actions and uniform clamping force. The adjusting block 31 on the clamping member 30 is provided with a slider adapted to the sliding groove 21. Specifically, in the initial state, the adjusting block 31 of the clamping member 30 is located within the corresponding sliding groove 21, and the clamping block 33 extends outward towards the clamping space, forming a released state. Next, the drive block 40 moves upward, driving the first connecting frame 51 and the second connecting frame 52. At this time, the clamping member 30 also slides synchronously along the sliding direction within the sliding groove 21, and the clamping block 33 retracts inward, completing the clamping. Then the drive block 40 moves down, the clamping member 30 slides in the opposite direction along the slide groove 21, and the clamping block 33 extends outward to complete the release.

[0040] Specifically, such as Figure 3As shown in this embodiment of the present invention, the mounting block 32 is provided with a mounting hole, and the clamping block 33 is provided with a fixing hole. The mounting hole and the fixing hole are connected and used for fasteners to pass through and lock, so as to fix the clamping block 33 on the mounting block 32. Specifically, the fixing hole of the clamping block 33 is aligned with the mounting hole of the mounting block 32, a fastener (such as a screw, bolt, etc.) is inserted, and the fastener is locked to achieve a reliable connection between the clamping block 33 and the mounting block 32. At the same time, if the clamping block 33 needs to be replaced or repaired, the clamping block 33 can be removed from the mounting block 32 simply by loosening the fastener, which is easy to operate.

[0041] Specifically, such as Figure 2-3 As shown in this embodiment of the invention, the first mounting base 10 is rotatably equipped with a lead screw 60 via a mounting bracket 12. The lead screw 60 is arranged vertically and threadedly connected to the drive block 40. The first mounting base 10 is equipped with a motor 70, the output end of which is connected to one end of the lead screw 60 to drive the lead screw 60 to rotate. Specifically, the motor 70 starts and drives the lead screw 60 to rotate. Since the drive block 40 is threadedly connected to the lead screw 60, when the lead screw 60 rotates, the drive block 40 moves linearly vertically along with the lead screw 60. For example, when the motor 70 controls the lead screw 60 to rotate in the forward direction, the drive block 40 moves upward, driving the clamping member 30 to retract inward through the first connecting bracket 51 and the second connecting bracket 52, clamping the glass bottle; when the motor 70 rotates in the reverse direction, the drive block 40 moves downward, and the clamping member 30 extends outward, releasing the glass bottle.

[0042] Specifically, such as Figure 1-3 As shown in this embodiment of the invention, the first mounting base 10 has a stepped surface 11 for supporting the glass bottle. The bottom of the second mounting base 20 extends outward to form an outer flange 22, and the outer flange 22 is provided with multiple bolt holes for reliably mounting and fixing the second mounting base 20 to the equipment table.

[0043] Example 2

[0044] like Figure 4 As shown, this utility model embodiment provides a polishing device, including the clamping device for pharmaceutical glass bottles described in Embodiment 1 above, a worktable 80, and a polishing mechanism 90 disposed on the worktable 80 for polishing the mouth of the pharmaceutical glass bottle. The clamping device is disposed on the worktable 80. The specific structure of the clamping device is as described in the above embodiment. Since this polishing device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0045] Specifically, in this embodiment, the polishing mechanism 90 includes a frame 91 disposed on the worktable 80, a lifting component 92 disposed on the frame 91, and a polishing component 93 disposed on the lifting component 92. To improve polishing flexibility, in another embodiment, the polishing mechanism 90 further includes a transverse component, with the frame 91 disposed on the transverse component to achieve lateral movement for comprehensive polishing of the mouth of the pharmaceutical glass bottle. Both the lifting component 92 and the transverse component can employ conventional linear drive mechanisms from the prior art, without any limitations in this embodiment's description, such as cylinders, hydraulic cylinders, or electric cylinders, as long as they can drive the polishing component 93 to slide in the longitudinal or transverse direction. The polishing components are conventional devices in the art, and since this invention does not make any improvements to them, their specific structure and operation will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
