Description

Technical Field

[0001] This invention relates to the field of glass bottle production technology, and specifically to a vulcanization apparatus for glass bottle production. Background Technology

[0002] To improve the physicochemical properties of glass bottles, vulcanization is a common process in glass bottle production. Vulcanization involves placing the glass bottle under high temperature and pressure, using a vulcanizing agent to induce a chemical reaction on its surface or inside. This process significantly improves the quality and reliability of the glass bottles. However, during the movement of the conveyor belt, the glass bottle remains stationary relative to it. Whether the bottle is placed vertically or horizontally, gravity causes the vulcanizing liquid on the inner wall of the bottle to move downwards. This results in uneven distribution of the vulcanizing liquid in the vertical direction, affecting the uniformity of the vulcanization effect and consequently impacting the consistency of the overall product performance. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that existing vulcanizing devices for glass bottle production lack the ability to drive the glass bottle to rotate, and to propose a vulcanizing device for glass bottle production.

[0004] To solve the above-mentioned technical problems, the present invention provides a vulcanization device for glass bottle production, including a frame, a conveying mechanism disposed on the frame, and a spraying mechanism mounted on the frame. The conveying mechanism includes two drive rollers rotatably disposed at both ends of the frame, a conveyor belt sleeved between the two drive rollers, and a drive motor drivenly connected to one of the drive rollers. The spraying end of the spraying mechanism sprays vulcanizing liquid onto the inner wall of the glass bottle by facing the conveying path of the conveyor belt. A plurality of mounting plates are spaced apart along the conveying direction on the conveyor belt. Each mounting plate is rotatably connected to a clamping component for detachably clamping the glass bottle. A drive component is also disposed on the frame. The drive component is drivenly connected to all the clamping components to drive all the clamping components to rotate synchronously around their own axes during the process of the conveyor belt carrying the glass bottle, thereby driving the clamped glass bottle to rotate synchronously.

[0005] Furthermore, the drive assembly includes a transmission chain, a gear, and two toothed plates. The transmission chain is disposed on one side of the conveyor belt, and the gear is correspondingly and fixedly disposed on each of the clamping assemblies, with the gear meshing with the outer peripheral teeth of the transmission chain. The two toothed plates are respectively sleeved on the outer periphery of the rotating shafts of the two transmission rollers, and both toothed plates are fixedly connected to the frame. The transmission chain is sleeved between the two toothed plates, and the inner periphery of the transmission chain meshes with the outer periphery of the two toothed plates.

[0006] Furthermore, the two toothed plates have the same diameter, and the line connecting the centers of the two toothed plates is parallel to the conveying direction of the conveyor belt.

[0007] Furthermore, the clamping assembly includes a rotating shaft rotatably connected to the mounting plate and fixedly connected to the gear, a plurality of radially extending slide rails disposed at the end of the rotating shaft away from the gear and spaced apart circumferentially along the rotating shaft, clamping members correspondingly disposed on each slide rail and slidable along the length direction of the slide rail, and an adjustment assembly disposed on the rotating shaft for driving the plurality of clamping members to move synchronously toward or away from each other.

[0008] Furthermore, a support frame is provided on the rotating shaft, and the adjustment assembly includes a turntable and an electric push rod. The turntable is rotatably connected to the end of the rotating shaft away from the gear, and the electric push rod is hinged to the support frame. The extension and retraction direction of the electric push rod is consistent with the rotation direction of the turntable, and the output end of the electric push rod is hinged to the turntable. The turntable has strip-shaped holes at the positions corresponding to the positions of the clamping members. Each clamping member is slidably inserted into the corresponding strip-shaped hole. The electric push rod drives the turntable to rotate, causing the positions of the strip-shaped holes to change. Then, through the sliding cooperation between the strip-shaped holes and the clamping members, the clamping members are driven to slide along the corresponding slide rails.

[0009] Furthermore, the clamping member includes a sliding sleeve disposed near one end of the slide rail, a drive rod fixedly connected to the sliding sleeve, and a clamping plate fixedly connected to the end of the drive rod away from the sliding sleeve; the sliding sleeve slides in cooperation with the slide rail to enable the clamping plate to slide along the slide rail, the drive rod slides through the strip hole, and the clamping plate is used to fit against the outer wall of the glass bottle to achieve clamping and positioning of the glass bottle.

[0010] Furthermore, a first hinge seat is fixedly installed on the mounting bracket, the electric push rod is hinged to the first hinge seat, a second hinge seat is fixedly installed on the outer periphery of the turntable, and the output end of the electric push rod is hinged to the second hinge seat.

[0011] Furthermore, each of the clamping plates is provided with an anti-slip rubber pad on the side facing the glass bottle.

[0012] Furthermore, the spraying mechanism includes a spraying needle, a storage tank, and a moving component. The spraying needle is connected to the storage tank, and the moving component is used to control the spraying needle to reciprocate relative to the conveyor belt, with the direction of movement parallel to the axis of the glass bottle.

[0013] Furthermore, the moving component is a cylinder, which is fixedly connected to the frame. The spray needle is fixedly disposed on the output end of the cylinder. The output direction of the cylinder is consistent with the axial direction of the glass bottle. There are multiple spray needles, and the arrangement direction of the multiple spray needles is consistent with the arrangement direction of the multiple glass bottles.

[0014] This invention provides a vulcanization device for glass bottle production. By incorporating detachable clamping components on a conveyor belt to hold the glass bottles, and using a drive assembly to propel all clamping components to rotate synchronously around their own axes during transport, it effectively solves the problem in existing technologies where the glass bottles are stationary relative to the conveyor, causing the vulcanizing liquid to move downwards along the inner wall due to gravity and resulting in uneven distribution. Combined with a spraying mechanism featuring a spray needle that reciprocates parallel to the glass bottle's axis, it further ensures uniform coverage of the vulcanizing liquid on the inner wall of the glass bottle, significantly improving the uniformity of the vulcanization effect and thus guaranteeing the consistency of the overall product performance. Simultaneously, the clamping components can be adjusted to accommodate glass bottles of different sizes, and the clamping plates are equipped with anti-slip rubber pads, ensuring clamping stability and the integrity of the glass bottles while enhancing the device's versatility. The overall structural design balances transport efficiency and vulcanization quality, making it highly practical. Attached Figure Description

Detailed Implementation

[0020] The following detailed description illustrates the specific implementation method: Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This invention discloses a vulcanizing apparatus for glass bottle production, comprising a frame 1, a conveying mechanism 2 mounted on the frame 1, and a spraying mechanism 3 mounted on the frame 1. The conveying mechanism 2 includes two drive rollers 21 rotatably mounted at both ends of the frame, a conveyor belt 22 sleeved between the two drive rollers 21, and a drive motor 23 drivenly connected to one of the drive rollers 21. The spraying end of the spraying mechanism 3 sprays vulcanizing liquid onto the inner wall of the glass bottle by facing the conveying path of the conveyor belt 22. A plurality of mounting plates 221 are spaced apart along the conveying direction on the conveyor belt 22. Each mounting plate 221 is rotatably connected to a clamping assembly 4 for detachably clamping the glass bottle. A drive assembly 5 is also mounted on the frame 1, and the drive assembly 5 is drivenly connected to all the clamping assemblies 4 to drive all the clamping assemblies 4 to rotate synchronously around their own axes during the conveying of the glass bottle by the conveyor belt 22, thereby causing the clamped glass bottle to rotate synchronously.

[0021] When using this vulcanizing device, the glass bottle to be processed must first be clamped and fixed by the clamping assembly 4. The clamping assembly 4 is rotatably connected to the mounting plate 221 of the conveyor belt 22, and its core structure includes a rotating shaft 41, a slide rail 42, a clamping member 43, and an adjusting assembly 44. One end of the rotating shaft 41 is rotatably connected to the mounting plate 221, and the other end is fixedly connected to the gear 52 to realize power transmission. The slide rail 42 is circumferentially spaced along the end of the rotating shaft 41 away from the gear 52 and extends radially, providing sliding guidance for the clamping member 43. The clamping member 43 consists of a sliding sleeve 431, a drive rod 432, and a clamping plate 433. The sliding sleeve 431 is slidably engaged with the slide rail 42. One end of the drive rod 432 is fixed to the sliding sleeve 431, and the other end is connected to the clamping plate 433. The drive rod 432 slides through the slot 4411 of the turntable 441. The clamping plate 433 is provided with an anti-slip rubber pad 4331 on the side facing the glass bottle, which can enhance the clamping stability and avoid damage to the outer wall of the glass bottle.

[0022] To accommodate glass bottles of different sizes, the clamping assembly 4 is equipped with an adjustment assembly 44, which includes a turntable 441 and an electric push rod 442. The turntable 441 is rotatably connected to the end of the rotating shaft 41 away from the gear 52. The electric push rod 442 is hinged to the support frame 411 of the rotating shaft 41 via a first hinge seat 4111. Its extension and retraction direction is consistent with the radial direction of the turntable 441, and its output end is hinged to the turntable 441 via a second hinge seat 4412. During adjustment, the electric push rod 442 is activated, and its extension and retraction end drives the turntable 441 to rotate around the rotating shaft 41. The strip hole 4411 deflects with the turntable 441, and through sliding cooperation with the drive rod 432, pushes several clamping members 43 to move closer or further away along the corresponding slide rail 42 until the anti-slip rubber pad 4331 is tightly attached to the outer wall of the glass bottle. Closing the electric push rod 442 completes the clamping and fixing.

[0023] After the glass bottle is clamped, the conveying mechanism 2 is activated. The drive motor 23 drives the transmission roller 21 connected to it to rotate, which in turn drives the conveyor belt 22 sleeved between the two transmission rollers 21 to rotate. The mounting plate 221 drives the clamping assembly 4 and the glass bottle to move along the conveying path. When the glass bottle enters the spraying area, the spraying mechanism 3 starts working. The spraying mechanism 3 includes a spray needle 31, a storage tank, and a moving assembly 32. The storage tank is connected to the spray needle 31 to provide the sulfiding liquid. The moving assembly 32 is a cylinder 321, which is fixedly connected to the frame 1. The spray needle 31 is fixed to the output end of the cylinder 321, and the output direction of the cylinder 321 is consistent with the axial direction of the glass bottle. To achieve simultaneous processing of multiple glass bottles, multiple spray needles 31 are provided, and their arrangement direction is consistent with the arrangement direction of the glass bottles. During the spraying process, the cylinder 321 drives the spray needle 31 to extend into the glass bottle and move back and forth along the axial direction to ensure that the sulfided liquid evenly covers the inner wall of the glass bottle. The sulfided liquid in the storage tank is continuously sprayed onto the inner wall through the spray needle 31.

[0024] Please continue reading Figure 1To increase the uniformity of the sulfide layer thickness adhering to the inner wall of the glass bottle, this application uses the drive assembly 5 to drive all clamping assemblies 4 and the glass bottle to rotate synchronously during the conveying process. Specifically, the drive assembly 5 includes a transmission chain 51, a gear 52, and two toothed plates 53. The transmission chain 51 is disposed on one side of the conveyor belt 22, and the gear 52 is correspondingly fixed on the rotating shaft 41 of each clamping assembly 4, and the gear 52 meshes with the outer peripheral teeth of the transmission chain 51. The two toothed plates 53 are respectively sleeved on the outer periphery of the rotating shafts of the two transmission rollers 21, and both toothed plates 53 are fixedly connected to the frame 1. The transmission chain 51 is sleeved between the two toothed plates 53, and the inner periphery of the transmission chain 51 meshes with the outer periphery of the two toothed plates 53. Furthermore, in this embodiment, the two toothed plates 53 have the same diameter, and the center line connecting the two toothed plates 53 is parallel to the conveying direction of the conveyor belt 22. This design allows the transmission chain 51 to form a stationary meshing track parallel to the conveyor belt 22 after being fitted. This avoids meshing misalignment caused by the tilting of the transmission chain 51, and ensures that the gear 52, when moving with the mounting plate 221, generates a stable relative meshing motion with the fixed transmission chain 51. This drives the gear 52 to rotate around its own axis, ensuring smooth rotation of the glass bottle and uniform adhesion of the vulcanizing liquid. During operation, the first drive motor 23 of the conveying mechanism 2 drives the transmission roller 21 to rotate, thereby driving the conveyor belt 22. The mounting plate 221 drives the clamping assembly 4 and the gear 52 to move along the conveying direction. Since the transmission chain 51 is kept stationary by the two fixed toothed plates 53, the gear 52 moves and meshes with the transmission chain 51, thereby driving the gear 52 to rotate around its own axis, which in turn drives the rotating shaft 41 of the clamping assembly 4 and the glass bottle to rotate synchronously. Under the action of centrifugal force, the sulfidation liquid is evenly attached to the inner wall of the glass bottle, effectively avoiding the problem of dripping.

[0025] The working principle of the vulcanization device for glass bottle production of the present invention is as follows: First, the glass bottle to be processed is placed in the clamping area of ​​the clamping assembly 4. The electric push rod 442 of the adjusting assembly 44 is activated. Its telescopic end drives the turntable 441 to rotate around the rotating shaft 41 through the cooperation of the first hinge seat 4111 and the second hinge seat 4412. The strip hole 4411 on the turntable 441 is deflected as it rotates. Through the sliding cooperation with the drive rod 432 of the clamping member 43, multiple clamping members 43 are pushed to move synchronously towards the glass bottle along the corresponding radial slide rail 42 until the anti-slip rubber pad 4331 on the clamping plate 433 is tightly attached to the outer wall of the glass bottle, so as to achieve stable fixation of glass bottles of different sizes. Then, the drive motor 23 of the conveying mechanism 2 is activated. The drive motor 23 drives the transmission roller 21 connected to it to rotate, which in turn drives the conveyor belt 22 sleeved between the two transmission rollers 21 to run smoothly. The mounting plate 221 on the conveyor belt 22 synchronously drives the clamping assembly 4 and the fixed glass bottle to move along the preset conveying path. When the glass bottle moves to the spraying area, the spraying mechanism 3 is activated. The sulfided liquid in the storage tank is transported to multiple spray needles 31 through pipelines. Simultaneously, the cylinder 321 of the moving component 32 drives the spray needles 31 to move towards the bottle opening and extend into the interior. The cylinder 321 also drives the spray needles 31 to reciprocate along the axial direction of the glass bottle, ensuring that the sulfided liquid can fully cover all areas of the inner wall of the glass bottle. After the sulfided liquid is sprayed, the drive motor 23 continuously drives the transmission roller 21 to rotate, the conveyor belt 22 runs smoothly, and the mounting plate 221 synchronously drives the clamping component 4 and the gear 52 to move along the conveying direction. During the movement of the gear 52, a stable relative meshing motion is generated with the fixed transmission chain 51, which in turn drives the rotating shaft 41 of the clamping component 4 and the clamped glass bottle to rotate synchronously and smoothly around their own axis, so that the sulfided liquid sprayed onto the inner wall is evenly spread under the action of centrifugal force.

[0026] The vulcanizing device for glass bottle production of the present invention has the following beneficial effects: The clamping component 4 drives the turntable 441 to rotate through the electric push rod 442 of the adjusting component 44, which can drive the clamping part 43 to move synchronously closer or further away along the slide rail 42, which can flexibly adapt to glass bottles of different sizes and specifications without the need to change special clamps. In addition, the clamping plate 433 of the clamping part 43 is provided with an anti-slip rubber pad 4331 on the side facing the glass bottle, which not only enhances the clamping stability and effectively avoids the bottle slipping and collision during transportation and rotation, but also protects the outer wall of the bottle from scratch damage, greatly improving the versatility of the device and the product qualification rate. The spraying mechanism 3 adopts a multi-spray needle design, and the arrangement direction of the multiple spray needles 31 is consistent with the arrangement direction of the glass bottle. With the axial reciprocating movement driven by the cylinder 321 in the moving component 32, the spray needles 31 can be inserted into the glass bottle and fully cover all areas of the inner wall, ensuring that the vulcanizing liquid is initially uniformly adhered, avoiding the problem of local missed spraying or uneven spraying, and laying a good foundation for the subsequent vulcanization quality. The drive assembly 5 is fixed to the frame 1 via two toothed plates 53 of the same diameter, whose center line is parallel to the conveying direction of the conveyor belt 22, forming a fixed meshing track for the transmission chain 51 fitted between the two toothed plates 53. When the conveyor belt 22 moves the mounting plate 221, the clamping assembly 4, and the gear 52, the gear 52 and the fixed transmission chain 51 generate a stable relative meshing motion, thereby driving the rotating shaft 41 of the clamping assembly 4 and the glass bottle to rotate synchronously and smoothly. This structure relies on the drive motor 23 of the conveying mechanism 2 for power, eliminating the need for additional complex drive units, significantly simplifying the equipment structure and enabling continuous batch operation. Simultaneously, the vulcanizing liquid is evenly spread under centrifugal force, effectively solving the problem of the vulcanizing liquid shifting downwards due to gravity, resulting in a more uniform distribution of the vulcanizing liquid on the inner wall of the glass bottle and improving the vulcanization effect.

[0027] The above are merely embodiments of the present invention, and common knowledge such as specific structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention, without affecting the effectiveness of the implementation of the present invention or its practicality.
