Description

Technical Field

[0001] This utility model belongs to the field of glass bottle processing technology, and in particular relates to a glass bottle acid washing device. Background Technology

[0002] In the production process of frosted glass, acid etching is the key step to achieve the frosted effect on the glass surface. Usually, a mixed acid etching solution, such as hydrochloric acid and hydrofluoric acid, is used to etch the surface of the glass bottle, so that the glass surface forms a uniform micro-rough structure, thus presenting a translucent frosted texture.

[0003] Existing glass bottle pickling equipment often employs a step-by-step process, first spraying the outer surface and then cleaning the inner wall in the next step. This requires repeated clamping and positioning of the glass bottles, making the operation cumbersome and inefficient. During this process, pickling solution easily remains on the surface and inside of the glass bottles after pickling, especially at the bottom and neck bends, where liquid tends to accumulate and is difficult to drain naturally. Residual solution can cause excessive etching of the frosted layer, resulting in excessively thick local frosted layers or spots, affecting the uniformity of appearance. At the same time, residual acidic substances may penetrate the glass surface, reducing the mechanical strength of the bottle and increasing the breakage rate during subsequent processing.

[0007] Optionally, the drive mechanism includes a movable frame slidably connected to two pairs of slide rails.

[0008] Optionally, the movable frame (401) is internally rotatably connected to a first screw, the outer end of which is threadedly connected to a first slider.

[0009] Optionally, a second motor and a third motor are fixedly connected to the top two sides of the movable frame, respectively. The output end of the second motor is connected to the first screw drive, and the output end of the third motor is connected to the second screw drive. A pneumatic telescopic rod is fixedly connected to the outer end of the movable frame, and the base of the pneumatic telescopic rod is fixedly connected to the inner wall of the box.

[0010] Optionally, an exhaust hood is fixedly connected to the top of the tank, a water tank is fixedly connected to the bottom side of the tank, a pump is fixedly connected to one side of the top of the water tank, the input end of the pump is connected to the water tank through a pipe, and a drain pipe is installed on the other side of the bottom of the tank.

[0011] Optionally, a four-way connector is fixedly connected to the top of the first movable frame. Three ports of the four-way connector are connected to three spray heads through pipes. A three-way connector is installed at the inlet end of the four-way connector through a pipe. The other two ends of the three-way connector are connected to the bottom end of the flushing rod and the output end of the pump through pipes.

[0012] Optionally, a conveying mechanism is also included, comprising a ring chain conveyor disposed on the bottom side of the housing, with one side of the ring chain conveyor extending into the interior of the through hole.

[0013] Optionally, the outer side of the annular chain conveyor is provided with an annular moving trough, and several double cylinders are slidably connected inside the annular moving trough.

The outer side of the connecting blocks is fixedly connected to several double cylinders.

[0015] This utility model has the following advantages and beneficial effects: This invention achieves simultaneous cleaning of the inner and outer surfaces of glass bottles within the same workstation by setting a drive mechanism between two pairs of slide rails and arranging an outer cleaning component and an inner cleaning component on both sides of the slide rails, allowing them to approach and separate along the same vertical axis. Compared with existing processes that process the outer surface first and then the inner surface in steps, this significantly reduces clamping and cross-process alignment errors, shortens cycle time, and improves overall line efficiency and consistency.

[0016] The external cleaning components combine "rotating bottle body + multi-roller scrubbing + external spray rinsing" to enhance the coverage and fluid disturbance of the transition area of ​​the bottle shoulder and the recessed area of ​​the bottle bottom, promote the breaking of the liquid film and the removal of residual liquid, and reduce the risk of residual acid retention, over-corrosion and spots on the outer surface.

[0017] The internal cleaning component uses a top-down rinsing rod with spray holes evenly distributed on its top and outer wall, enabling close-range directional spraying of the bottle neck, shoulder, and bottom. The internal and external sprays create a counter-current and shearing effect at the turning points, shortening the drainage path, promoting natural drainage, and significantly reducing liquid accumulation at the bottle bottom and neck. This inhibits localized over-etching, uneven thickness, and spots on the frosted layer, improving the uniformity of the appearance.

[0018] In summary, this solution reduces repeated clamping and residual acid retention caused by step-by-step cleaning, reduces the risk of liquid accumulation, over-etching, and spots at the bottom and neck of the bottle, improves appearance consistency and strength retention, reduces the breakage rate in subsequent processing, and enables continuous and rhythmic production.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Example like Figures 1 to 7 As shown, a glass bottle acid washing device includes a main body 1 and a washing device. The main body 1 includes a housing 101, and a through hole 102 is provided on one side of the housing 101 to allow glass bottles to enter and exit and connect with the conveying mechanism 2.

[0024] The cleaning device includes two pairs of slide rails 3, which are fixedly connected to the inner side of the housing 101. A drive mechanism 4 is slidably connected between the two pairs of slide rails 3. The cleaning device also includes an outer cleaning assembly 5 and an inner cleaning assembly 6. The drive mechanism 4 is used to drive the outer cleaning assembly 5 and the inner cleaning assembly 6 to move closer to or separate from each other, thereby performing simultaneous acid washing on the inner and outer surfaces of the glass bottle, reducing repeated clamping and cross-process alignment errors, and improving cleaning efficiency and consistency.

[0025] like Figures 3-5As shown, the external cleaning assembly 5 further includes a cleaning frame 501 fixedly connected to the drive mechanism 4. A stop block 502 is rotatably connected to the center of the bottom end of the cleaning frame 501, and several cleaning rollers 503 are also rotatably connected to the bottom end. Several spray heads 504 are fixedly connected to the outer wall of the cleaning frame 501. A first motor 505 is fixedly connected to the top of the cleaning frame 501; an acid- and corrosion-resistant motor must be selected. Its output shaft passes through the cleaning frame 501 and is fixedly connected to the stop block 502; a first gear 506 is fixedly fixed to the output shaft. Second gears 507 are respectively fixed to the outer ends of the central shafts of the several cleaning rollers 503, and the second gears 507 mesh with the first gears 506.

[0026] The first motor 505 drives the first gear 506 to rotate, and through meshing with the second gear 507, all the cleaning rollers 503 rotate synchronously to perform high-frequency scrubbing on the outer surface of the glass bottle. At the same time, the output shaft of the first motor 505 is rigidly coaxially connected to the abutment block 502. As the first motor 505 rotates, it drives the abutment block 502 to rotate, causing the clamped and positioned glass bottle to rotate accordingly. Thus, under the combined action of the mechanical scrubbing of the cleaning rollers and the liquid rinsing of the spray head 504, the transition area of ​​the bottle shoulder and the concave area of ​​the bottle bottom are cleaned, which improves the cleaning coverage and residual liquid removal capacity, and reduces the risk of acid retention and local over-corrosion.

[0027] The internal cleaning assembly 6 includes a rinsing rod 601 inserted into the drive mechanism 4. Spray holes are provided on the top end and outer wall of the rinsing rod 601, which sprays and rinses the inner wall of the bottle under the liquid supply of the pump.

[0028] The rinsing rod 601 can penetrate deep into the bottle cavity to spray the neck contraction section, shoulder transition and bottom backflow area at close range. It forms a coordinated internal and external rinsing with the external cleaning component 5, shortens the drainage path, accelerates liquid film breakage, reduces liquid accumulation at the bottom and neck of the bottle, helps natural drainage and inhibits appearance defects such as over-etching and spots on the sand layer.

[0029] Furthermore, the drive mechanism 4 includes a movable frame 401 that is slidably connected to two pairs of slide rails 3. The movable frame 401 is slidably connected to a first movable frame 402 and a second movable frame 403 on its outer side. The first movable frame 402 is fixedly connected to the cleaning frame 501, and the second movable frame 403 is used to install the rinsing rod 601, so as to realize the independent alignment and opposite / backward adjustment of the outer / inner cleaning components.

[0030] like Figure 4 and Figure 6As shown, a first screw 404 is rotatably connected inside the movable frame 401, and a first slider 406 is threadedly connected to the outer end of the first screw 404. A second screw 405 is also rotatably connected inside the movable frame 401, and a second slider 407 is threadedly connected to the outer end of the second screw 405. A movable block 408 is movably sleeved on the second screw 405. One end of the first slider 406 is fixedly connected to the movable block 408, and the other end of the movable block 408 is fixedly connected to the first movable frame 402. The other end of the second slider 407 is fixedly connected to the second movable frame 403. A first telescopic waterproof cover 409 is fixedly connected between the movable block 408 and the second slider 407; a second telescopic waterproof cover 410 is provided at the opposite ends of the movable block 408 and the second slider 407, and the opposite ends of a pair of second telescopic waterproof covers 410 are fixedly connected to the two ends inside the movable frame 401 respectively. The first screw 404 drives the first slider 406 and the movable block 408 to move, thereby adjusting the position of the first movable frame 402; the second screw 405 drives the second slider 407 to adjust the position of the second movable frame 403; the first telescopic waterproof cover 409 and the second telescopic waterproof cover 410 can prevent acid from seeping in, protect the transmission components, and ensure smooth adjustment.

[0031] Furthermore, a second motor 411 and a third motor 412 are fixedly connected to the top two sides of the movable frame 401, respectively. Both motors are preferably waterproof and corrosion-resistant. The output end of the second motor 411 is connected to the first screw 404, and the output end of the third motor 412 is connected to the second screw 405. The two motors drive the corresponding screws to rotate, thereby driving the first movable frame 402 and the second movable frame 403 to move linearly up and down along the movable frame 401, realizing precise alignment and spacing control of the outer cleaning component 5 and the inner cleaning component 6. A pneumatic telescopic rod 413 is fixedly connected to the outer end of the movable frame 401, and its base is fixedly connected to the inner wall of the housing 101. This rod is used to drive the movable frame 401 to reciprocate linearly along the slide rail 3, expanding the effective working range, adapting to different bottle types, and improving the working range and flexibility of the device.

[0032] Furthermore, an exhaust hood 103 is fixedly connected to the top of the housing 101 to collect acid mist and can be connected to an external negative pressure discharge system to collect harmful gases generated during pickling and prevent gas diffusion from polluting the environment; a water tank 104 is fixedly connected to the bottom side of the housing 101, and a pump 105 is fixedly connected to one side of its top. The input end of the pump 105 is connected to the water tank 104 through a pipe, and a drain pipe is installed on the other side of the bottom of the housing 101 for centralized discharge of waste liquid.

[0033] Furthermore, to simplify the liquid circuit and achieve synchronous liquid supply for internal and external spraying, a four-way connector 7 is fixedly connected to the top of the first movable frame 402. The three ports of the four-way connector 7 are respectively connected to several spray heads 504 through pipes; the inlet end of the four-way connector 7 is connected to a three-way connector 8 through a pipe, and the other two ends of the three-way connector 8 are respectively connected to the bottom end of the flushing rod 601 and the output end of the pump 105 through pipes.

[0034] The three-way connector 8 and the four-way connector 7 work together to divert the cleaning fluid delivered by the pump 105 to both the external and internal spraying systems. This reduces the number of pipes, simplifies the pipeline layout, reduces flow resistance fluctuations, and ensures uniform spraying and stable fluid supply to the nozzles or flushing rods 601.

[0035] like Figures 1-2 and Figure 7 As shown, it further includes a conveying mechanism 2. The conveying mechanism 2 includes a ring chain conveyor 201 installed on the bottom side of the housing 101, with one side extending into the through hole 102. The ring chain conveyor 201 of the conveying mechanism 2 can continuously convey glass bottles, sending them into the housing 101 for cleaning through the through groove 102. After cleaning, the bottles are conveyed out, realizing automated continuous operation, improving cleaning efficiency, and connecting with external workstations to complete the automatic entry and exit of glass bottles and the connection of cycle time.

[0036] Furthermore, an annular moving groove 208 is opened on the outer side of the annular chain conveyor 201, and several double cylinders 202 are slidably connected inside; both moving ends of the double cylinders 202 are fixedly connected to the fixing frames 203, and a pair of clamping rollers 204 are fixedly connected to the facing surfaces of each pair of fixing frames 203. The clamping rollers 204 are preferably made of fluororubber. The annular moving groove 208 guides the double cylinders 202 to move stably; the double cylinders 202 drive the fixing frames 203 to drive the clamping rollers 204 to clamp the glass bottle. The fluororubber material is resistant to acid corrosion and does not damage the surface of the glass bottle, ensuring the stability of the glass bottle during the conveying process and avoiding tipping or displacement.

[0037] Furthermore, both sides of the internal structure of the annular chain conveyor 201 are rotatably connected to sprockets 205, and a chain 206 is wound between a pair of sprockets 205. Several connecting blocks 207 are installed at equal intervals on the outer side of the chain 206. Each connecting block 207 is fixedly connected to a corresponding double cylinder 202. The sprockets 205 and the chain 206 cooperate to drive the connecting blocks 207 to move, thereby driving the double cylinder 202 and the glass bottles to be continuously conveyed along the annular track. The equally spaced connecting blocks 207 ensure that the glass bottles are conveyed at uniform intervals, ensuring that the pickling operation is carried out in an orderly manner.

[0038] like Figures 1 to 7As shown, the working principle of this glass bottle acid washing device is as follows: During production, the annular chain conveyor 201 runs under the drive of the sprocket 205, and drives the double cylinder 202 to move along the annular moving groove 208 via the connecting block 207. The double cylinder 202 pushes the fixed frame 203 to make the clamping roller 204 clamp the two sides of the glass bottle mouth, and the glass bottle is stably transported to the cleaning station in the box 101 through the through hole 102. The pneumatic telescopic rod 413 drives the movable frame 401 to move along the slide rail frame 3 to the target position. Subsequently, the second motor 411 and the third motor 412 drive the first screw 404 and the second screw 405 respectively. The first movable frame 402 drives the cleaning frame 501 to descend, and the second movable frame 403 drives the rinsing rod 601 to rise and extend into the bottle. The stop block 502 abuts against the bottom of the bottle and rotates with the first motor 505, causing the glass bottle to rotate. Pump 105 draws cleaning fluid from water tank 104 and distributes it through three-way valve 8 and four-way valve 7 to the spray nozzles of spray head 504 and rinsing rod 601, simultaneously spraying or rinsing the outside and inside of the bottle. First motor 505 drives first gear 506 to rotate synchronously with cleaning roller 503, creating a combined effect of all-around mechanical scrubbing and liquid rinsing with the rotation of the bottle body. This reduces residual liquid accumulation at the bottom and neck of the bottle, facilitates natural drainage, and inhibits over-etching and spots on the frosted layer. Acid mist generated during cleaning is collected under negative pressure by exhaust hood 103, and waste liquid is discharged centrally through drain pipe. After cleaning, conveying mechanism 2 automatically delivers the glass bottle out of box 101, completing the continuous acid washing operation.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
