Description

Technical Field

[0001] This invention relates to the field of glass tube feeding technology, and more specifically, to an automatic material changing device for processing borosilicate glass bottles. Background Technology

[0002] Borosilicate glass bottles, due to their excellent chemical stability and heat resistance, have become a core material in the pharmaceutical packaging field, widely used in the packaging of high-end pharmaceuticals such as vaccines and biological agents. The mainstream processing technology employs a secondary glass tube forming technique, using high-temperature flame cutting (fire cutting) to segment prefabricated glass tubes, simultaneously forming two sealed glass bottle preforms in a single cut. However, current fire cutting equipment is still primarily semi-automated, with key processes such as loading, unloading, positioning, and unloading heavily reliant on manual operation. As the pharmaceutical industry continues to demand higher standards for packaging material quality consistency, production safety, and efficiency, traditional processes are no longer sufficient to meet the needs of modern production lines for automation, intelligence, and large-scale processing.

[0003] Existing fire-cutting equipment has several technical drawbacks: First, manual loading and unloading requires operators to be exposed to high-temperature open flames for extended periods, posing a risk of burns and failing to meet occupational health regulations. Second, manual clamping and positioning relies on operator experience, which can easily lead to axial misalignment of the glass tube, resulting in uneven cutting surfaces and exceeding dimensional tolerances for the preform, directly impacting product yield. Third, the single-station, single-tube processing mode is inefficient and severely out of sync with the industry trend of multi-station parallel production. Furthermore, the intermittent nature of manual operation does not match the continuous processing characteristics of the equipment, resulting in low actual equipment utilization. Therefore, there is an urgent need to invent an automatic material changing device for borosilicate glass bottle processing to improve the processing efficiency of borosilicate glass bottles. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an automatic material changing device for processing borosilicate glass bottles.

[0005] The technical implementation of this invention is as follows: An automatic material changing device for processing borosilicate glass bottles includes a flame cutting machine body and a feeding rack. The flame cutting machine body is an existing high-temperature flame cutting equipment for processing glass bottles. The flame cutting machine body has two sets of workstations for clamping and processing glass bottles. A feeding rack is provided on one side of the flame cutting machine body for feeding glass bottles to the side of the flame cutting machine body. The top of the feeding rack is a feeding plate inclined towards the flame cutting machine body. The device also includes a mounting frame fixedly installed on the top of the flame cutting machine body. The top of the mounting frame is a square frame. Electric slide rails are symmetrically arranged inside the side wall of the top frame of the mounting frame. A sliding plate is slidably connected between the two sides of the electric slide rails. A cylinder is fixedly installed on the bottom surface of the sliding plate. An electric slide rail is horizontally fixedly mounted on the downward-facing extension rod of the cylinder. A mounting rod is vertically fixedly connected to the upper part of the housing of the electric slide rail facing the feeding rack. The mounting rod slides... A sliding frame is connected, parallel to the cylinder. An adjusting thread is provided at the end of the mounting rod near the cylinder. An adjusting nut is rotatably installed on the adjusting thread of the mounting rod. The adjusting nut is used to adjust the clamping position of the sliding frame, allowing the two sets of clamping claws to adapt to the clamping distance of the glass bottles in the bottom clamping area of ​​the unloading rack. An electric slide rail three is fixedly installed at the bottom of the sliding frame. A spring one is provided between the sliding frame and the end of the mounting rod. Two sets of clamping claws are installed on both the electric slide rail two and electric slide rail three, staggered from each other. The clamping claws are used to clamp the glass bottles on the flame-cutting machine body for material changing. Two vertically protruding baffles are symmetrically fixed to the top of the flame-cutting machine body. Stops that adapt to the baffles are symmetrically fixed to both ends of the bottom of the sliding frame. The baffles are used to position the sliding frame at the glass bottle clamping position on the flame-cutting machine body. A receiving rack for collecting processed glass bottles is provided on one side of the unloading rack.

[0006] Optionally, the clamping claw consists of a mounting block, an arc-shaped clamping block, a connecting block, and an electric push rod. Mounting blocks are slidably mounted on both the electric slide rails. Each mounting block is an arched block with arc-shaped clamping blocks symmetrically hinged to its lower two sides. A connecting block is slidably connected between the upper ends of the two arc-shaped clamping blocks. The two ends of the connecting block are grooves. The upper ends of the arc-shaped clamping blocks are respectively located in the grooves of the connecting block. An electric push rod is fixedly mounted on the upper part of the mounting block. The telescopic rod of the electric push rod is connected to the connecting block.

[0007] Optionally, a support plate is fixedly connected to the bottom of the feeding plate of the feeding rack, and a buffer plate is slidably connected to the side of the support plate near the feeding plate. A second spring is provided between the support plate and the buffer plate. Under the action of the second spring, the buffer plate can elastically buffer the glass bottles that slide to the bottom of the feeding rack, reducing the risk of breakage when the glass bottles roll to the bottom of the feeding rack. A slot is provided at the bottom of the feeding plate of the feeding rack, and a separator is provided in the slot at the bottom of the feeding rack. The separator is used to separate two glass bottles on the feeding rack, so that the clamping claw can smoothly clamp the glass bottles on the feeding rack.

[0008] Optionally, the isolation component includes a guide rod, a mounting frame, a partition block, a second electric push rod, and a threaded rod. The guide rod is fixedly connected to the bottom surface of the unloading plate of the unloading rack. The mounting frame is slidably connected to the guide rod. The partition block is slidably installed on the mounting frame. The partition block is located in a slot at the bottom of the unloading rack. The top of the partition block is an arc surface adapted to fit the glass bottle. The second electric push rod is fixedly installed at the bottom of the mounting frame. The telescopic rod of the second electric push rod passes through the mounting frame and is connected to the partition block. The bottom surface of the unloading plate of the unloading rack is also rotatably connected to a threaded rod, which is threadedly engaged with the mounting frame.

[0009] Optionally, the feeding plate of the feeding rack is provided with an intermittent feeding mechanism near the buffer plate. The intermittent feeding mechanism includes a cylindrical frame, a rhomboid shaft, star-shaped rotating blocks, and a motor. The cylindrical frame is provided near the bottom of the feeding plate of the feeding rack. The rhomboid shaft is rotatably connected inside the cylindrical frame. At least two star-shaped rotating blocks are slidably installed on the rhomboid shaft. The star-shaped rotating blocks have four arc grooves on their circumference for receiving glass bottles. The motor is fixedly installed on the outside of the feeding plate of the feeding rack. The output shaft of the motor passes through the feeding rack and is connected to the rhomboid shaft.

[0010] Optionally, the top surface of the feeding plate of the feeding rack is symmetrically and slidably connected with two limiting plates. The limiting plates are used to limit the glass bottles on the feeding rack. A bidirectional lead screw is rotatably connected to the middle of the bottom surface of the feeding plate of the feeding rack. The bidirectional threads of the bidirectional lead screw are respectively adapted to the threads of the limiting plates on both sides. A connecting sleeve is rotatably provided at the point where the limiting plate is penetrated by the rhomboid shaft. The connecting sleeve and the rhomboid shaft are slidably engaged. The limiting plate is rotatably engaged with the corresponding star-shaped rotating block on the same side through the connecting sleeve.

[0011] Optionally, each arc groove of the star-shaped rotating block is provided with an elastic cloth, and an adjustment shaft is rotatably connected to one side of the arc groove of the star-shaped rotating block. The end face of the adjustment shaft is provided with a groove adapted to a tightening tool. One end of the elastic cloth is wrapped around the adjustment shaft corresponding to the star-shaped rotating block, and the other end of the elastic cloth is fixed to the side of the arc groove of the star-shaped rotating block away from the adjustment shaft.

[0012] Optionally, the receiving rack consists of a base frame, a collecting frame, an electric slide rail four, and a sliding frame. The collecting frame is mounted on one side of the top of the base frame, and the electric slide rail four is fixedly installed on the other side of the top of the base frame. The sliding frame is slidably mounted on the electric slide rail four. The sliding frame can slide under the gripping claw under the drive of the electric slide rail four and collect the processed glass bottles in batches.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention combines an electric slide rail, a cylinder, and clamping claws, and adjusts the distance between the two sets of clamping claws with an adjusting nut to ensure that the clamping claws can safely grip glass bottles on the unloading rack. Then, baffles and blocks are used to position the workstation on the main body of the flame cutting machine, so that the clamping claws can accurately change materials on the main body of the flame cutting machine, thereby saving manual operation and improving production efficiency and automation level.

[0015] 2. The present invention provides a buffer plate at the bottom of the feeding rack and provides elastic cushioning with spring 2, which effectively reduces the risk of glass bottles breaking when they roll to the bottom. At the same time, the intermittent feeding mechanism further reduces the collisions and damage that may occur during the rolling of the glass bottles.

[0016] 3. The present invention can also adapt the device to glass bottles of different sizes and lengths by adjusting the position of the limiting plate and the design of the star-shaped rotating block, thereby enhancing the versatility and flexibility of the equipment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0030] Example 1: An automatic material changing device for processing borosilicate glass bottles, such as... Figures 1-5As shown, the device includes a flame cutting machine body 1 and a feeding rack 2. The flame cutting machine body 1 is an existing high-temperature flame cutting and processing equipment for glass bottles 100. The flame cutting machine body 1 has two sets of clamping and processing stations for the glass bottles 100. The feeding rack 2 is set on one side of the flame cutting machine body 1. The feeding rack 2 is used to feed the glass bottles 100 to the side of the flame cutting machine body 1. The top of the feeding rack 2 is a feeding plate that is inclined towards the flame cutting machine body 1. The device also includes a mounting frame 3 fixedly installed on the top of the flame cutting machine body 1. The top of the mounting frame 3 is a square frame. Electric slide rails 31 are symmetrically arranged inside the side wall of the top frame of the mounting frame 3. A sliding plate 4 is slidably connected between the two electric slide rails 31. The bottom surface of the sliding plate 4 A cylinder 5 is fixedly installed. The telescopic rod of the cylinder 5 is horizontally fixedly mounted with an electric slide rail 6 facing downwards. A mounting rod 7 is vertically fixedly connected to the upper part of the housing of the electric slide rail 6, facing the unloading rack 2. A sliding frame 9 is slidably connected to the mounting rod 7. The sliding frame 9 is parallel to the cylinder 5. An adjusting thread 8 is provided at the end of the mounting rod 7 near the cylinder 5. An adjusting nut 81 is rotatably installed at the adjusting thread 8 of the mounting rod 7. The adjusting nut 81 is used to adjust the clamping position of the sliding frame 9, so that the two sets of clamping claws 10 can adapt to the clamping distance of the glass bottle 100 in the bottom clamping area of ​​the unloading rack 2. An electric slide rail 3 91 is fixedly installed at the bottom of the sliding frame 9. The sliding frame 9 and the mounting rod 6... A spring 92 is provided between the ends of the rod 7. Two sets of clamping claws 10 are installed on the electric slide rails 6 and 91, and are staggered. The clamping claws 10 are used to clamp the glass bottle 100 on the flame cutter body 1 for material changing. Two vertically protruding baffles 11 are symmetrically fixed to the top of the flame cutter body 1. The bottom ends of the sliding frame 9 are symmetrically fixed with stop blocks 111 that are adapted to the baffles 11. The baffles 11 are used to position the sliding frame 9 at the position on the flame cutter body 1 where the glass bottle 100 is clamped. A receiving rack 18 is provided on one side of the unloading rack 2 for collecting the processed glass bottles 100. Before processing the glass bottle 100, the adjusting thread 8 is turned on the mounting rod 7. Adjusting nut 81 on the upper part adjusts the clamping distance of the clamping claws 10 on the electric slide rail 2 6 and electric slide rail 3 91. With the electric slide rail 1 31 driving the slide plate 4 to directly above the processing position of the flame cutter body 1, during this process, the baffle 11 will block and limit the stop block 111 on the sliding frame 9, so that the clamping claws 10 on the electric slide rail 2 6 and electric slide rail 3 91 can be accurately aligned with the two sets of work positions on the flame cutter body 1. Then, the cylinder 5 drives the clamping claws 10 on the electric slide rail 2 6 and electric slide rail 3 91 to descend to the work position of the flame cutter body 1. With the flame cutter body 1, the glass bottle 100 is clamped synchronously, and the automatic material changing operation of processing the glass bottle 100 can be completed.

[0031] like Figures 2-4As shown, the clamping claw 10 consists of a mounting block 101, an arc-shaped clamping block 102, a connecting block 103, and an electric push rod 104. Mounting blocks 101 are slidably mounted on both the electric slide rail 2 6 and the electric slide rail 3 91. Each mounting block 101 is an arched block with arc-shaped clamping blocks 102 symmetrically hinged to its lower sides. A connecting block 103 is slidably connected between the upper ends of the two arc-shaped clamping blocks 102. The two ends of the connecting block 103 are grooves 1031. The upper ends of 02 are respectively located in the sliding groove 1031 of the connecting block 103. An electric push rod 104 is fixedly installed on the upper part of the mounting block 101. The telescopic rod of the electric push rod 104 is connected to the connecting block 103. The telescopic rod of the electric push rod 104 drives the connecting block 103 to rise and fall, so that the sliding groove 1031 of the connecting block 103 can press the upper end of the arc-shaped clamping block 102, so that the arc-shaped clamping block 102 performs an expansion and contraction clamping action on the mounting block 101.

[0032] like Figure 1 and Figure 6 and Figure 11 As shown, the receiving rack 18 consists of a base frame 181, a collection frame 182, an electric slide rail 183, and a sliding frame 184. The collection frame 182 is mounted on one side of the top of the base frame 181, and the electric slide rail 183 is fixedly installed on the other side of the top of the base frame 181. The sliding frame 184 is slidably mounted on the electric slide rail 183. The sliding frame 184 can slide under the gripper 10 under the drive of the electric slide rail 183 and collect the processed glass bottles 100 in batches. Finally, the glass bottles 100 in the sliding frame 184 are transferred to the collection frame 182 to complete the centralized collection.

[0033] When processing glass bottle materials, the two clamping stations of the flame cutter body 1 will simultaneously perform high-temperature flame cutting of the glass bottles 100. Before changing materials, the adjusting nut 81 on the mounting rod 7 needs to be adjusted according to the spacing of the glass bottles 100 in the clamping area at the bottom of the unloading rack 2. By turning the adjusting nut 81 to the position of the adjusting thread 8 section of the mounting rod 7, the sliding frame 9 slides along the adjusting thread 8 section of the mounting rod 7 under the action of spring 92, thereby changing the spacing between the clamping claws 10 of the electric slide rail 3 91 and the electric slide rail 2 6. Spring 92 ensures that the sliding frame 9 maintains elastic pre-tension with the end of the mounting rod 7 after adjustment. Since the two sets of clamping claws 10 on the electric slide rail 3 91 and the electric slide rail 2 6 are staggered, the slide plate 4 can carry the cylinder 5 and the two below. The clamping claws 10 are adjusted to a suitable clamping distance for the glass bottles 100. When the glass bottles 100 to be processed roll from the inclined unloading plate of the unloading rack 2 to the side of the main body 1 of the fire-cutting machine, the clamping operation of the glass bottles 100 to be processed is then performed. When the sliding plate 4 is moved horizontally to the clamping area at the bottom of the unloading rack 2 by the electric slide rail 1 31 at the top of the mounting frame 3, the electric slide rail 2 6 and electric slide rail 3 91 are driven vertically by the cylinder 5, so that the clamping claws 10 are close to the glass bottles 100 in the clamping area on the unloading rack 2. At this time, the clamping claws 10 on the electric slide rail 2 6 and the electric slide rail 3 91 move synchronously, that is, the electric push rod 1 104 is activated to drive the connecting block 103 to rise. The sliding grooves 1031 at both ends of the connecting block 103 press the upper end of the arc-shaped clamping block 102, forcing The two arc-shaped clamping blocks 102, hinged to the lower part of the mounting block 101, retract inward to clamp the glass bottle 100. Then, the cylinder 5 synchronously drives the two sets of clamping claws 10 to clamp the glass bottle 100, reset and lift it. Then, the electric slide rail 1 31 drives the slide plate 4 to carry the cylinder 5 and the clamping assembly below to be precisely positioned above the processing station of the flame cutting machine body 1. During this positioning process, the baffle 11 at the top of the flame cutting machine body 1 physically blocks the stop block 111 at the bottom of the sliding frame 9, forcing the clamping claws 10 to be precisely aligned with the station of the flame cutting machine body 1. Then, the cylinder 5 pushes the electric slide rail 2 6 and electric slide rail 3 91 to descend vertically as a whole, so that the clamping claws 10 are aligned with the station of the flame cutting machine body 1. At this time, the operator only needs to control the positioning of the clamps on the station of the flame cutting machine body 1. Once the glass bottle 100 is picked up from the clamping claw 10, the main body 1 of the flame cutter clamps the glass bottle 100. The electric push rod 104 drives the connecting block 103 to descend, and the two arc-shaped clamping blocks 102 at the bottom of the mounting block 101 open outwards, causing the clamping claw 10 to open simultaneously and release the glass bottle 100 from the workstation. Then, the cylinder 5 drives the clamping claw 10 to rise and reset. After the main body 1 of the flame cutter completes the cutting of the glass bottle 100, the cylinder 5 again drives the clamping claw 10 to move downwards and clamp the processed glass bottle 100. The operator then releases the clamps at the workstation of the main body 1 of the flame cutter, allowing the clamping claw 10 to pick up the processed glass bottle 100 again. Simultaneously, the electric slide rail 183 of the receiving rack 18 drives the sliding frame 184 to move horizontally to directly above the clamping area of ​​the unloading rack 2.Subsequently, the electric slide rail 31 drives the clamping claw 10 under the sliding plate 4 to return to the clamping area of ​​the unloading rack 2. Finally, the cylinder 5 drives the clamping claw 10 to move down to the sliding frame 184, causing the clamping claw 10 to release the processed glass bottle 100 into the sliding frame 184. The sliding frame 184, loaded with the processed glass bottle 100, will then return to the collection frame 182, facilitating the collection personnel to transfer the glass bottles 100 from the sliding frame 184 to the collection frame 182. This completes the efficient material changing operation of the glass bottle 100.

[0034] Example 2: Based on Example 1, such as Figure 6 and Figure 8 As shown, a support plate 12 is fixedly connected to the bottom of the feeding plate of the feeding rack 2. A buffer plate 13 is slidably connected to the side of the support plate 12 near the feeding plate. A spring 131 is provided between the support plate 12 and the buffer plate 13. Under the action of the spring 131, the buffer plate 13 can elastically buffer the glass bottle 100 that slides to the bottom of the feeding rack 2, reducing the risk of the glass bottle 100 breaking when it rolls to the bottom of the feeding rack 2. A slot is provided at the bottom of the feeding plate of the feeding rack 2. A separator 14 is provided in the slot at the bottom of the feeding rack 2. The separator 14 is used to separate the two glass bottles 100 on the feeding rack 2, so that the clamping claw 10 can smoothly clamp the glass bottle 100 on the feeding rack 2.

[0035] like Figure 7 and Figure 8 As shown, the separator 14 includes a guide rod 141, a mounting frame 142, a partition block 143, a second electric push rod 144, and a threaded rod 145. The guide rod 141 is fixedly connected to the bottom surface of the unloading plate of the unloading rack 2. The mounting frame 142 is slidably connected to the guide rod 141. The partition block 143 is slidably mounted on the mounting frame 142. The partition block 143 is located in a slot at the bottom of the unloading rack 2. The top of the partition block 143 is an arc surface adapted to fit the glass bottle 100. The second electric push rod 144 is fixedly mounted at the bottom of the mounting frame 142. The telescopic rod of the second electric push rod 144 passes through the mounting frame 142 and connects to the partition block 143. The bottom surface of the unloading plate of the unloading rack 2 also... A threaded rod 145 is rotatably connected to the mounting frame 142. The threaded rod 145 is threadedly engaged with the mounting frame 142. By turning the threaded rod 145, the position of the partition block 143 on the mounting frame 142 can be adjusted so that the partition block 143 can be adapted to the partition of glass bottles 100 of different sizes. When the electric push rod 144 drives the partition block 143 to descend below the unloading plate of the unloading rack 2, the glass bottles 100 on the unloading rack 2 can roll down to the buffer plate 13. When the electric push rod 144 drives the partition block 143 to protrude on the unloading plate of the unloading rack 2, the two glass bottles 100 that are tightly attached to the bottom of the unloading rack 2 can be separated, which is convenient for the subsequent clamping claw 10 to perform safe clamping.

[0036] like Figure 1 , Figure 7 and Figure 9As shown, an intermittent feeding mechanism 15 is provided on the feeding plate of the feeding rack 2 near the buffer plate 13. The intermittent feeding mechanism 15 includes a cylindrical frame 151, a rhomboid shaft 152, a star-shaped rotating block 153, and a motor 154. The cylindrical frame 151 is provided near the bottom of the feeding plate of the feeding rack 2. The rhomboid shaft 152 is rotatably connected inside the cylindrical frame 151. Two star-shaped rotating blocks 153 are slidably mounted on the rhomboid shaft 152. The star-shaped rotating blocks 153 have four arc grooves around their circumference to receive the glass bottles 100. A motor 154 is fixedly installed on the outside of the feeding plate of the feeding rack 2. The output shaft of the motor 154 passes through the feeding rack 2 and is connected to the rhomboid shaft 152. The glass bottles 100 arranged and sliding down the feeding plate of the feeding rack 2 can be inserted into the circular groove of the star-shaped rotating block 153. With the help of the motor 154, the star-shaped rotating block 153 on the rhomboid shaft 152 is driven to rotate intermittently, so that the glass bottles 100 in the circular groove of the star-shaped rotating block 153 can be intermittently released to the bottom of the feeding plate of the feeding rack 2, further reducing the risk of breakage when the glass bottles 100 roll down.

[0037] like Figures 6-8 As shown, the top surface of the feeding plate of the feeding rack 2 is symmetrically and slidably connected with two limiting plates 16. The limiting plates 16 are used to limit the glass bottles 100 on the feeding rack 2. A bidirectional screw 161 is rotatably connected to the middle of the bottom surface of the feeding plate of the feeding rack 2. The bidirectional threads of the bidirectional screw 161 are respectively adapted to the threads of the limiting plates 16 on both sides. A connecting sleeve 162 is rotatably provided at the point where the limiting plate 16 is penetrated by the rhomboid shaft 152. The connecting sleeve 162 and the rhomboid shaft 152 are slidably engaged. The limiting plate 16 is rotatably engaged with the corresponding star-shaped rotating block 153 on the same side through the connecting sleeve 162. Tightening the bidirectional screw 161 can simultaneously adjust the position of the two limiting plates 16 on the feeding plate of the feeding rack 2, so that the limiting plates 16 can adapt to the limiting of glass bottles 100 of different lengths. At the same time, the limiting plates 16 can push the corresponding star-shaped rotating block 153 to slide and adjust on the rhomboid shaft 152, so that the star-shaped rotating block 153 can also adapt to glass bottles 100 of different lengths.

[0038] like Figure 9 and Figure 10 As shown, each arc groove of the star-shaped rotating block 153 is provided with an elastic cloth 17. An adjusting shaft 171 is rotatably connected to one side of the arc groove of the star-shaped rotating block 153. The end face of the adjusting shaft 171 is provided with a groove adapted to the turning tool. One end of the elastic cloth 17 is wrapped around the corresponding adjusting shaft 171 of the star-shaped rotating block 153, and the other end of the elastic cloth 17 is fixed to the side of the arc groove of the star-shaped rotating block 153 away from the adjusting shaft 171. The tool is inserted into the groove of the adjusting shaft 171. By turning the adjusting shaft 171 to wind the elastic cloth 17, the elastic cloth 17 in the arc groove of the star-shaped rotating block 153 can change its elasticity, thereby adapting to the receiving action of glass bottles 100 of different sizes.

[0039] When the glass bottles 100 placed sequentially on the feeder 2 roll along the inclined feeder plate, the buffer plate 13, supported by the elasticity of spring 131, offsets the impact of the bottles, preventing the glass bottles 100 from breaking due to rigid collision with the feeder 2 in the clamping area. When the glass bottles 100 stop in the clamping area of ​​the feeder 2, the separator block 143 of the separator 14 is driven by the electric push rod 144 to rise from the slot at the bottom of the feeder 2, and its top arc surface is embedded into the gap between two adjacent bottles, forcibly separating the closely arranged bottles. Glass bottles 100 are clamped to ensure that the clamping claws 10 can only hold single bottles during subsequent clamping. The threaded rod 145 is turned to drive the mounting frame 142 to slide along the guide rod 141, allowing the separator block 143 to adapt to the clamping requirements of bottles of different sizes. Simultaneously, the motor 154 of the intermittent feeding mechanism 15 drives the rhomboid shaft 152 to rotate, causing the star-shaped rotating block 153 to rotate periodically. During rotation, the four arc grooves of each star-shaped rotating block 153 sequentially receive the glass bottles 100 rolling off the feeding plate. The elastic cloth 17 pre-installed in the groove cushions the bottle's downward inertia by wrapping it around the bottle body. When the arc groove rotates to its lowest point with the rotating block, the bottle body is released to the buffer plate 13, achieving controllable intermittent feeding. When processing glass bottles 100 of different lengths, the bidirectional lead screw 161 can be rotated. The bidirectional lead screw 161 drives the two side limit plates 16 on the feeding rack 2 to slide symmetrically, so that the limit plates 16 can adapt to the limiting feeding of glass bottles 100 of different lengths. At the same time, the moving limit plates 16 will be connected to the continuous The connecting sleeve 162 pushes the star-shaped rotating block 153 to move laterally along the rhomboid shaft 152, so that the spacing of the arc grooves of multiple sets of star-shaped rotating blocks 153 matches the length of the glass bottle 100. If it is necessary to adjust the tension of the elastic cloth 17, the tool can be inserted into the groove of the adjusting shaft 171 and rotated. By winding or releasing the elastic cloth 17, the wrapping tightness of the arc groove can be changed, thereby adapting to the stable support of bottles of different sizes, so that the unloading rack 2 can better adapt to the clamping operation of the clamping claw 10, and improve the safety of the device during automatic material changing.
