Description

Technical Field

[0001] The invention relates to a bottle making machine and a blanking and straightening mechanism thereof. Background Art

[0002] After firing, the finished glass bottles in existing bottle-making machines drop vertically downward from the last station, passing through an inclined chute that extends downward toward the conveyor belt before sliding onto the conveyor belt. During this sliding process, due to the high production speed of the bottle-making machine, the glass bottles slide one by one onto the conveyor belt with their mouths facing downward. Existing conveyor belts are equipped with anti-collision pads on one side to prevent the glass bottles from cracking or even breaking due to the strong impact when sliding onto the conveyor belt. However, this unloading method causes the glass bottles to fall onto the conveyor belt in an irregular and scattered manner, necessitating the subsequent deployment of specialized workers to collect and stack the individual glass bottles. This results in significant labor costs and reduces production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a blanking and straightening mechanism to solve the problem in the prior art that glass bottles cannot be stacked neatly when blanking, resulting in low production efficiency; the purpose of the present invention is also to provide a bottle making machine with the blanking and straightening mechanism.

[0004] In order to solve the above problems, the blanking and straightening mechanism involved in the present invention adopts the following technical solutions:

[0005] The blanking and straightening mechanism includes a bottle collecting trough for extending a direction parallel to the conveying direction of the conveyor belt when installed, the bottle collecting trough having a U-shaped cross-section, the upstream end of the bottle collecting trough being closed, and an opening for communicating with the tail end of the inclined chute of the bottle making machine is provided on the side wall of the bottle collecting trough corresponding to the opening, and an anti-collision pad is provided on the side wall of the bottle collecting trough on the other side. The straightening mechanism also includes a rotating shaft rotatably arranged on the side wall of the bottle collecting trough and extending horizontally, the axis of the rotating shaft being perpendicular to the extension direction of the bottle collecting trough, and a straightening plate for extending toward the inside of the bottle collecting trough being fixed on the rotating shaft. The straightening plate has an avoidance position that swings upward toward the upstream end of the material collecting trough to avoid sliding in glass bottles in the process of following the rotation of the rotating shaft, and also has a shifting position that swings from upstream to downstream to shift the glass bottle bodies entering the bottle collecting trough and straighten the glass bottles for collection downstream, and the rotation is configured with a driving mechanism for driving the rotating shaft to rotate.

[0006] Furthermore, the driving mechanism includes a stepping motor for driving the rotating shaft to rotate forward and reverse, and also includes a speed reduction mechanism connected between the stepping motor and the rotating shaft.

[0007] Furthermore, the width of the bottle collecting groove is not greater than 1.5 times the length of the glass bottle.

[0008] Furthermore, the inclined chute and the bottle collecting trough are detachably connected.

[0009] Furthermore, the bottom of the straightening plate is connected to a receiving plate for receiving the glass bottle, and the lower end of the receiving plate is recessed downward.

[0010] The bottle making machine involved in the present invention adopts the following technical solutions:

[0011] The bottle making machine includes a machine body and an inclined chute arranged at the discharge position of the machine body and extending toward the conveyor belt. The tail end of the inclined chute is connected to a blanking and squaring mechanism, including a bottle collecting trough for extending in a direction parallel to the conveying direction of the conveyor belt when installed. The cross section of the bottle collecting trough is U-shaped, the upstream end of the bottle collecting trough is closed, and an opening for communicating with the tail end of the inclined chute of the bottle making machine is provided on the side wall of the bottle collecting trough on the other side of the corresponding opening. The squaring mechanism also includes a rotating device. A rotating shaft is provided on the side wall of the bottle collecting trough and extends horizontally, and the axis of the rotating shaft is perpendicular to the extension direction of the bottle collecting trough. A squaring plate is fixed on the rotating shaft and is used to extend toward the interior of the bottle collecting trough. The squaring plate has an avoidance position for swinging upward toward the upstream end of the collecting trough to avoid the glass bottles sliding in during the rotation of the rotating shaft. The squaring plate also has a swaying position for swinging from upstream to downstream to sway the glass bottles entering the bottle collecting trough and squaring the glass bottles downstream for collection. The rotating shaft is provided with a driving mechanism for driving the rotating shaft to rotate.

[0012] Furthermore, the driving mechanism includes a stepping motor for driving the rotating shaft to rotate forward and reverse, and also includes a speed reduction mechanism connected between the stepping motor and the rotating shaft.

[0013] Furthermore, the width of the bottle collecting groove is not greater than 1.5 times the length of the glass bottle.

[0014] Furthermore, the inclined chute and the bottle collecting trough are detachably connected.

[0015] Furthermore, the bottom of the straightening plate is connected to a receiving plate for receiving the glass bottle, and the lower end of the receiving plate is recessed downward.

[0016] The beneficial effects of the present invention are as follows: Compared to the prior art, the drop and straightening mechanism of the present invention, during actual use, after a glass bottle drops from the inclined chute and enters the bottle collecting trough at a certain speed, the impact force of the glass bottle is offset by the energy absorption of the anti-collision cushion. At this time, the glass bottle is located in the bottle collecting trough, and at the same time, the driving mechanism drives the straightening plate to rotate or swing during operation. During the swinging process from upstream to downstream, the glass bottle that has just dropped and is located on the upper rear side of the bottle collecting trough is pushed forward. The glass bottle is forced to be pushed to the front end of the bottle collecting trough to achieve straightening. Afterwards, the straightening plate is driven back to the avoidance position to wait for the next glass bottle to drop. Since the bottle making speed of the bottle making machine is generally constant, it is only necessary to set the driving speed of the driving mechanism to ensure that the straightening plate can move a glass bottle forward as soon as a glass bottle drops. The operation is relatively simple. After the glass bottles are collected to a certain extent, they automatically fall onto the conveyor belt and continue to be transported forward. The setting of the straightening mechanism does not consume manpower, has low cost, and has a simple structure, ensuring that each glass bottle is in a straightened posture when it is sent to the conveyor belt.

[0021] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The specific embodiment of the blanking and straightening mechanism involved in the present invention is as follows: Figure 1 and Figure 2 As shown, the blanking and straightening structure is installed between a conveyor belt 1 and the body of the bottle making machine. The conveyor belt 1 is defined as conveying in an upstream-to-downstream direction. The bottle making machine includes a body and an inclined chute 2 disposed at the discharge position of the body. The inclined chute 2 extends downwardly and obliquely toward the conveyor belt 1, and the extension direction of the inclined chute 2 is perpendicular to the conveying direction of the conveyor belt 1. The axis of the finished glass bottle 10 is aligned with the extension direction of the inclined chute 2, and the finished glass bottle 10 slides onto the conveyor belt 1 through the inclined chute 2.

[0023] The straightening mechanism includes a bottle collecting trough 3 that, when installed, extends parallel to the conveying direction of the conveyor belt 1. The bottom wall of the trough 3 is suspended above the conveyor belt 1. The trough 3 has a U-shaped cross-section, with the upstream end closed, forming a box-like structure with an open downstream end. An opening 5 is provided on the sidewall of the trough 3, near the closed end, for communication with the rear end of the inclined chute 2. The bottom wall of the trough 3 smoothly connects with the rear end bottom wall of the inclined chute 2, allowing glass bottles 10 to slide smoothly into the trough 3. A soft impact pad 4 is also provided on the sidewall opposite the opening 5. The impact of the glass bottles 10 is offset by the energy absorption provided by the impact pad 4. This prevents the glass bottles 10 from breaking or cracking due to the strong impact of sliding down. At the same time, the straightening mechanism also includes a rotating shaft 6 that is rotatably arranged on the side wall of the bottle collecting trough 3 and extends horizontally. The axis of the rotating shaft 6 is perpendicular to the extension direction of the bottle collecting trough 3. A straightening plate 7 is fixed on the rotating shaft 6 for extending toward the interior of the bottle collecting trough 3. The straightening plate 7 has an avoidance position that swings upward toward the upstream end of the collecting trough to avoid the glass bottle 10 that slides in during the rotation of the rotating shaft 6. It also has a moving position that swings from upstream to downstream to move the glass bottle 10 that enters the bottle collecting trough 3 and straightens the glass bottle 10 for collection downstream. The rotation is configured with a driving mechanism for driving the rotating shaft 6 to rotate.

[0024] Furthermore, in this embodiment, the drive mechanism includes a stepper motor 9 for driving the rotating shaft 6 in forward and reverse rotation, and a reduction mechanism connected between the stepper motor 9 and the rotating shaft 6. By selecting the appropriate reduction mechanism, the alignment frequency of the alignment plate 7 is aligned with the frequency at which the glass bottles 10 fall into the bottle collecting trough 3, ensuring that each glass bottle 10 is properly moved while preventing collisions between the glass bottles 10. Of course, in other embodiments, a unidirectional motor could also be used to drive the alignment plate 7 to continuously swing in one direction, moving one glass bottle 10 per cycle.

[0025] Specifically, a bearing seat is provided on the edge of the conveyor belt 1, and a bearing 8 is provided in the bearing seat. The rotating shaft 6 is rotatably assembled on the conveyor belt 1 through the bearing 8, thereby supporting the rotating shaft 6, and the driving mechanism is fixed on the body of the bottle making machine.

[0026] In addition, the width of the bottle collecting groove 3 is not greater than 1.5 times the length of the glass bottle 10. This can satisfy the moving space of the glass bottle 10 and simultaneously avoid the inability of the straightening plate 7 to accurately contact the glass bottle 10 when it is moved.

[0027] In addition, the inclined chute 2 and the bottle collecting trough 3 are detachably connected. This arrangement is mainly to allow the bottle collecting trough 3 to be replaced according to the actual size of the glass bottles 10. Of course, the specific detachable connection can be achieved through rivets, bolts, snaps, etc.

[0028] After the glass bottle 10 falls from the inclined chute 2 and enters the bottle collecting trough 3 at a certain speed, the impact force of the glass bottle 10 is offset by the energy absorption of the anti-collision cushion 4. At this time, the glass bottle 10 is located in the bottle collecting trough 3. At the same time, the driving mechanism drives the straightening plate 7 to rotate or swing during operation. During the swing from upstream to downstream, the glass bottle 10 that has just fallen and is located on the upper and rear side of the bottle collecting trough 3 is pushed forward. The glass bottle 10 is pushed to the front end of the bottle collecting trough 3 by the force, and is straightened. After that, the straightening plate 7 is driven back to the avoidance position to wait for the next glass bottle 10 to fall. Since the bottle making speed of the bottle making machine is generally constant, it is only necessary to set the driving speed of the driving mechanism to ensure that the straightening plate 7 can move a glass bottle 10 forward as soon as a glass bottle 10 falls. The operation is relatively simple. After the glass bottles 10 are collected to a certain extent, the glass bottles 10 automatically fall onto the conveyor belt 1 and continue to be conveyed forward. The setting of the straightening mechanism does not consume manpower, has low cost, and has a simple structure, ensuring that each glass bottle 10 is in a straightened posture when it is sent to the conveyor belt 1.

[0029] In other embodiments, the bottom of the straightening plate is connected to a receiving plate for receiving glass bottles, and the lower end of the receiving plate is recessed. When the straightening plate reaches the avoidance position, the receiving plate is exactly located at the opening of the inclined chute, and the straightening plate is located in front of the inclined chute. The straightening plate then swings forward, reaching a certain angle, and the glass bottles slide off the receiving plate.

[0030] Of course, in other embodiments, the driving mechanism may also be in the form of a hydraulic cylinder, which drives the cam to rotate during the extension and retraction process, thereby driving the straightening rod to move.

[0031] An embodiment of the bottle making machine involved in the present invention includes a machine body and an inclined chute arranged at the discharge position of the machine body and extending toward the conveyor belt. The tail end of the inclined chute is connected to a blanking and straightening mechanism. The structure of the blanking and straightening mechanism is consistent with the structure in the above-mentioned embodiment of the blanking and straightening mechanism and will not be elaborated on in detail.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate and not to limit the technical solutions of the present invention. Any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
