Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of packaging machinery, and particularly relates to a bottle separating mechanism with a screw rod quick replacement mechanism and a label sleeving device. BACKGROUND

[0002] The label sleeving device can automatically cut off the label strip and accurately sleeve the label strip, and cooperates with a subsequent heat shrinkage process to fix the label strip on the cylindrical container. The label sleeving device has excellent high-speed stability performance. Nowadays, automatic high-speed label sleeving devices have been widely applied in the fields of food, beverage, daily-use chemical industry and pharmaceutical industry.

[0003] Bottle separating mechanisms with bottle separating screws are known. For example, a bottle separating device is known from the Chinese utility model patent CN215556960U, which comprises a rack, a drive motor, two screw rods rotatably supported on the rack, the two screw rods being arranged with their axes parallel to each other and forming a bottle separating channel for the passage of containers between the two screw rods, wherein the two screw rods are of the same construction and each have an input shaft on which a first gear of the same construction is fixedly arranged, and a second gear is arranged on the output shaft of the drive motor, the second gear being coupled to the first gears by a transmission mechanism designed as a double-sided tooth synchronous belt, the two first gears being arranged on the inner and outer sides of the double-sided tooth synchronous belt, so that the drive motor can simultaneously drive the two screw rods to rotate in opposite directions at the same speed. In addition, a bottle separating mechanism with a single screw rod is also known, which comprises a bottle separating screw, a track stopper arranged in parallel with the bottle separating screw, and a conveying mesh belt arranged below the bottle separating screw and the track stopper, the track stopper being spaced apart from the bottle separating screw to form a passage for bottles, and one end of the bottle separating screw being connected to a power source through a transmission mechanism.

[0004] However, whether it is a double-screw rod bottle separating mechanism or a single-screw rod bottle separating mechanism, the screw rod can only be designed for a specific size of container, and the screw rod needs to be replaced in the case of a change in the size of the container to be sleeved with a label or in the case of wear and tear of the screw rod. However, replacing the screw rod in the existing bottle separating mechanism is very time-consuming and requires a long time for installation and adjustment.

[0005] Therefore, there is an urgent need to improve the existing bottle separating mechanism and the corresponding label sleeving device to make the structure more reasonable and enable quick replacement. UTILITY MODEL CONTENTS

[0006] The utility model aims to provide a bottle separating mechanism with a screw rod quick replacement mechanism and a label sleeving device, which can achieve quick replacement of the screw rod with a simple structure.

[0007] The above technical problem is solved by a bottle separating device with a screw rod quick change mechanism, the bottle separating device having at least one screw rod, a base and a support mechanism for rotatably supporting the screw rod at both ends of the screw rod, wherein at least one support mechanism is designed as a screw rod quick change mechanism, the screw rod quick change mechanism comprising a L-shaped movable support and a fixed support which is fixedly connected to the base, the movable support comprising a first leg which is parallel to the longitudinal direction of the screw rod and a second leg which is perpendicular to the first leg, the first leg being detachably connected to the fixed support, a bearing for receiving a screw rod spindle being provided on the second leg at an end which is adjacent to the end side of the screw rod. Here, the bottle separating device can comprise a single screw rod or two screw rods which cooperate with each other. The at least one screw rod is supported by the support mechanism which is designed as a screw rod quick change mechanism. By quickly releasing the fixed connection between the first leg and the fixed support, the L-shaped movable support can be moved, so that the screw rod can be quickly detached and installed, the entire process being completed within a short time, for example, 30 seconds to 1 minute, greatly improving the work efficiency compared to the prior art.

[0008] According to an advantageous embodiment, a first through-hole is configured on the first leg, a threaded connection being able to pass through the first through-hole to fixedly connect the first leg with the fixed support, the first through-hole being designed as a slot, the diameter of the rod of the threaded connection being smaller than the width of the slot. By configuring the first through-hole as a slot and the diameter of the rod of the threaded connection being smaller than the width of the slot, the threaded connection allows the first leg to move after being released while still being in the connected position with the fixed support, so that after replacing the screw rod, it is not necessary to align the threaded connection again, thereby further shortening the time required for the readjustment process after installing the screw rod.

[0009] It is also preferred that the first leg is connected with the fixed support by means of a snap connection. For this purpose, for example, a recess is provided on the first leg and a locking tongue is provided on the fixed support. By moving the first leg into a predetermined snap position, the locking tongue is snapped into the recess to form a snap lock.

[0010] It is also preferred that the first leg and the second leg are integrally configured. Thereby, an L-shaped movable support which is simple in structure and easy to process is achieved.

[0011] It is also advantageous that the first leg and the second leg are separately configured, a second through-hole being provided on the second leg, a bolt passing through the second through-hole to fixedly connect the first leg and the second leg, the second through-hole being designed as a slot which extends in the longitudinal direction perpendicular to the screw rod, the diameter of the rod of the bolt being smaller than the width of the second through-hole. Thereby, an additional adjustment possibility in the transverse direction perpendicular to the longitudinal direction of the screw rod is added, so that it is possible to adapt to screw rods of different diameters or so that the bottle separating device can be applied to a wider range of containers.

[0012] Another advantage is that a handle is provided at the head of the threaded connector. This allows for quick manual installation or removal of the screw.

[0013] Preferably, the end of the screw mandrel opposite the L-shaped movable support is designed to complement the shape of the mandrel receiving seat. Therefore, when this end of the mandrel is inserted into the mandrel receiving seat, a form-locking connection capable of transmission is formed.

[0014] Preferably, the spindle receiving seat is fixedly connected to or integrally formed with the rotating shaft, which is rotatably supported by a support mechanism. The rotating shaft is supported, for example, in bearings fixed in the support mechanism, particularly in two spaced-apart bearings.

[0015] In one advantageous embodiment, a transmission gear is fixed to the rotating shaft in a manner that prevents relative rotation, and this transmission gear is mechanically connected to the drive mechanism. This allows for power introduction with a simple structure.

[0016] This utility model also proposes a labeling device, which includes a labeling mechanism and a main heat shrink oven. The labeling device also has the aforementioned bottle-separating mechanism with a screw quick-change mechanism.

[0017] In the square bottle mechanism with a quick-change screw structure according to this application, the screw can be replaced by loosening the connection between the L-shaped movable support and the fixed support fixed on the base. This achieves quick installation or replacement of the screw with a simple structure. Furthermore, the use of an elongated hole ensures that the threaded connection remains secure during the movement of the L-shaped movable support, avoiding the time required for re-alignment and tightening of the threaded connection. It also accommodates screws of different lengths. Overall, this significantly reduces the time required for screw replacement and reinstallation (specifically, reducing it from at least 3-5 minutes in the prior art to 30 seconds to 1 minute), improving work efficiency.

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0023] On the existing sleeve labeling pipeline, the containers are usually transported one by one to the sleeve labeling position through a conveyor belt or a conveying chain and the sleeve labeling is completed at the sleeve labeling position. For this purpose, a bottle separating mechanism with a bottle separating screw is required to be arranged before the sleeve labeling position so as to separate the batch transported bottles at a specified interval and sequentially transport them to the sleeve labeling position. However, due to different specifications of the containers and wear of the bottle separating screw after long time use, the screw needs to be replaced frequently. In the existing scheme, the screw dismounting and reinstallation adjustment are very complicated and a lot of time is consumed. Therefore, the application proposes a bottle separating mechanism with a screw quick replacement mechanism.

[0024] Figure 1A bottle separating mechanism 100 with a screw rod quick change mechanism according to an advantageous embodiment of the application is shown. The bottle separating mechanism 100 comprises a screw rod 1, a base 2 and a support mechanism fixed on the base. The support mechanism is designed to support the screw rod 1. The bottle separating mechanism 100 shown here comprises only one screw rod 1. However, the bottle separating mechanism 100 can also comprise two screw rods which are arranged parallel to each other and cooperate with each other. The two screw rods are identically designed in terms of their construction and their support. The base 2 is fixed on the frame of a labelling machine, for which purpose a plurality of fixing holes are provided on the base. One of the support mechanisms is designed as a screw rod quick change mechanism. The screw rod quick change mechanism comprises an L-shaped movable support 3 and a fixed support 4. The fixed support 4 is fixedly arranged on the base 2. The L-shaped movable support 3 comprises a first leg 6 and a second leg 7. The first leg 6 is detachably connected to the fixed support 4, in particular by means of a screw connection 8. The screw connection 8 is for example a screw, a bolt or a stud. A first through-hole 9 is formed in the first leg 6, which first through-hole 9 extends through the first leg 6. The first through-hole 9 is designed as a long hole which extends parallel to the longitudinal direction of the screw rod. The diameter of the screw connection 8 is smaller than the width of the first through-hole. This means that, in the case of a loosened screw connection, that is to say, the screw connection 8 remains in the connected state with the fixed support 4, but does not clamp the first leg 6 relative to the fixed support 4, the first leg 6 can be moved relative to the screw connection and the fixed support 4. A handle 10 can also be provided on the head of the screw connection 8. The second leg 7 is connected to the first leg 6 and arranged perpendicular thereto. A bearing 5 for receiving the screw rod spindle is arranged on the end of the second leg 7 which is located near the screw rod end. The bearing 5 is for example inserted in a through-hole formed on the end of the second leg 7. Although not shown, the first leg can also be connected to the fixed support in a detachable manner by means of a snap connection.

[0025] In Figure 1 In the solution shown, the L-shaped movable support 3 is designed as a two-part design, wherein the first leg 6 and the second leg 7 are designed as separate parts. The second leg 7 is fixedly connected to the first leg by means of a screw. In addition, a second through-hole is also formed in the second leg 7, which second through-hole is designed as a long hole which extends perpendicular to the longitudinal direction of the screw rod. The screw passes through the second through-hole to fixedly connect the first leg and the second leg, the diameter of the screw rod being smaller than the width of the second through-hole. In this way, the relative movement of the second leg 7 with respect to the first leg 6 is also allowed in the case of a partially loosened screw. This additionally provides a lateral adjustability, so that for example the overhanging length of the first leg 6 can be adjusted when a larger diameter screw rod is installed. However, the first leg and the second leg can also be simply formed in one piece.

[0026] Figure 2 In the solution shown, Figure 1Fig. 2 shows a top view of the bottle separating mechanism. Fig. 3 shows a perspective view of the bottle separating mechanism. Figure 2 The manner of the engagement between the L-shaped movable support 3 and the fixed support 4 can be clearly seen, specifically the first leg 6 of the L-shaped movable support 3 is partially inserted into the opening of the fixed support 4. The screw rod 1 is received in the mandrel receiving seat 11 at the end away from the screw rod quick switching mechanism. The mandrel and the mandrel receiving portion 11 are designed complementarily in shape. Thus, a form-locked connection is formed when the mandrel 15 is inserted into the mandrel receiving portion 11, which can be used for transmission, that is, the power for rotating the screw rod 1. The mandrel receiving portion 11 is fixedly connected or integrally formed with the rotating shaft 14. The rotating shaft 14 is rotatably supported by a support mechanism in the form of a first support plate 12 and a second support plate 13. For example, through holes are respectively provided in the first support plate 12 and the second support plate 13, and bearings are arranged in each through hole. A transmission gear is fixedly arranged on the rotating shaft 11 in a manner that cannot rotate relative to the rotating shaft 11, and the transmission gear is mechanically connected with a driving mechanism, which is not shown.

[0027] Figure 3 Fig. 4 shows a perspective view of the screw rod 1. In order to facilitate the entry of the container, the inlet end of the screw rod 1 is designed to be tapered, and the length of the taper is 10%-20% of the total length. The outlet end of the screw rod 1 is designed to be variable pitch, and gradually increases the pitch at an equal acceleration law until the pitch increases to the desired distance. Overall, the pitch of the screw rod 1 gradually increases from the inlet end to the outlet end. At least one transverse protrusion 16, preferably two mutually symmetrical transverse protrusions vertically outwardly protruding from the peripheral surface of the mandrel 15, is arranged on the mandrel 15 at the inlet end of the screw rod 1. The transverse protrusion can be clamped into the corresponding groove of the mandrel receiving seat.

[0028] Figure 4 Fig. 5 shows a perspective view of the mandrel receiving seat 11 for receiving the mandrel of the screw rod end. The mandrel receiving seat 11 is fixedly connected with the rotating shaft 14. A groove for receiving the mandrel is arranged at the end side of the mandrel receiving seat 11, and the profile of the groove is designed complementarily with the profile of the mandrel and the transverse protrusion arranged on the mandrel. Thus, a form-locked force transmission connection can be formed in the state that the mandrel is connected with the mandrel receiving seat.

[0029] The utility model discloses still disclose a kind of sleeve label equipment. The sleeve label equipment includes sleeve label mechanism and main heat shrinkage furnace, wherein, the sleeve label equipment further has the bottle separating mechanism with screw rod quick replacement mechanism as described before. In the sleeve label equipment of the present application, by the combination L-shaped movable support and the fixed support fixed on base, by the connection between movable support and fixed support is loosened, screw rod replacement can be realized. Thus, with simple structure, the quick installation or replacement of screw rod is realized. Here, the time required for replacing and reinstalling screw rod can be shortened to 30 seconds-1 minute, and work efficiency is greatly improved. In addition, by setting long hole, the adjustment flexibility in transverse and longitudinal direction is improved, so that it can be applied to screw rod of different length or diameter, so it can be used for the bottle separating manipulation of different size containers.
