Description

Technical Field

[0001] The present invention relates to the field of carton gluing machines, and particularly to a mechanism for controlling the movement of a belt plate of a carton gluing machine. Background Art

[0002] Generally, a fixed lead screw sleeve is used to control the movement of the belt plate in a carton gluing machine. Therefore, two mutually linked lead screws and supporting parts need to be installed separately for each belt plate. As shown in Figure 1 Figure 13, the belt plate is moved by rotating a number of corresponding lead screws 13. When using a motorized belt plate, an independent DC small motor and related electrical components need to be equipped for each belt plate. The large number of machine parts results in high manufacturing and installation costs, and the supporting parts are relatively large in size, occupying the internal space of the machine, and thus limiting the maximum size of the box shape that the machine can produce. Summary of the Invention

[0003] An object of the present invention is to provide a mechanism for controlling the movement of a belt plate of a carton gluing machine to overcome the above-mentioned defects existing in the prior art.

[0004] The object of the present invention can be achieved by the following technical solutions:

[0005] A mechanism for controlling the movement of a belt plate of a carton gluing machine includes a lead screw, on which an auxiliary lead screw sleeve disc, a preloading spring, a main lead screw sleeve disc, an armature and an electromagnetic brake are sequentially sleeved from top to bottom. Among them, the preloading spring coaxially penetrates into the main lead screw sleeve disc, and the armature is fixedly connected to the main lead screw sleeve disc through a connecting positioning pin.

[0006] Preferably, a tight fixing positioning pin for fixedly connecting with the main lead screw sleeve disc to cooperate with clamping the belt plate is further provided on the auxiliary lead screw sleeve disc.

[0007] Preferably, a spacer sleeve for reducing friction is further sleeved on one end of the tight fixing positioning pin.

[0008] Preferably, a thrust washer for axial positioning and a limit plate are sequentially sleeved coaxially below the electromagnetic brake.

[0009] Preferably, a self-lubricating bearing is coaxially penetrated into the inner hole of the electromagnetic brake.

[0010] Preferably, an internal hexagonal countersunk head screw for cooperating with the connecting positioning pin to fixedly connect with the main lead screw sleeve disc is further provided on the armature.

[0011] Preferably, the tensile strength of the preloading spring is 965 N / mm 2 ~1267 N / mm 2 .

[0012] Preferably, the connecting and positioning pin is a connecting and positioning pin in the shape of a circular column.

[0013] Preferably, the number of the connecting and positioning pins is two.

[0014] Preferably, the auxiliary lead screw sleeve disc is further provided with a round hole for bolt fixation with the box gluing machine.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) By sleeving the main lead screw sleeve disc and the auxiliary lead screw sleeve disc on the lead screw and applying elastic force through the pre-tightening spring to press the box gluing machine belt plate and moving the belt plate by rotation, a large number of electrical and mechanical parts are reduced, and the cost is lowered.

[0017] (2) All the parts sleeved on the lead screw are small in volume and are interconnected and fixed by positioning pins. Therefore, when installed on the box gluing machine, the occupied space is small, and the sizes of the products that can be produced are more and wider.

[0018] (3) The number of lead screws and the number of other electrical and mechanical parts are reduced. The necessary parts required are only the main and auxiliary sleeve discs, one lead screw, and an electromagnetic brake, etc., and the installation is simpler and faster.

[0019] (4) All the parts sleeved on the lead screw are small in volume and are interconnected and fixed by positioning pins. Therefore, the structure of the whole box gluing machine is simplified and the aesthetics is increased. Description of the Drawings

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 2 shown in the figure is the overall structural schematic diagram of a mechanism for controlling the movement of the belt plate of a box gluing machine according to the present invention, including a lead screw 13. An auxiliary lead screw sleeve disc 10, a preloading spring 14, a main lead screw sleeve disc 2, an armature 9, and an electromagnetic brake 4 are sequentially sleeved on the lead screw 13 from top to bottom. Among them, a self-lubricating bearing 8 is coaxially inserted into the inner hole of the electromagnetic brake 4. A round hole for bolt fixation with the box gluing machine is also provided on the auxiliary lead screw sleeve disc 10. The tensile strength of the preloading spring 14 is 965 N / mm 2 ~1267 N / mm 2 , a thrust washer 6 for axial positioning and a limit plate 5 are coaxially sleeved below the electromagnetic brake 4 in sequence. The preloading spring 14 coaxially passes through the main lead screw sleeve disc 2. The armature 9 is fixedly connected to the main lead screw sleeve disc 2 through a connecting positioning pin 1. An internal hexagonal countersunk head screw 3 for cooperating with the connecting positioning pin 1 to fixedly connect with the main lead screw sleeve disc 2 is also provided on the armature 9. The number of connecting positioning pins 1 is 2 and its shape is a circular columnar body. A fastening positioning pin 11 for fixedly connecting with the main lead screw sleeve disc 2 to cooperate with clamping the belt plate is also provided on the auxiliary lead screw sleeve disc 10. A spacer sleeve 12 for reducing friction is sleeved at one end of the fastening positioning pin 11 to be fixedly connected with the auxiliary lead screw sleeve disc 10.

[0027] The basic installation steps of the present invention are as follows: After installing the self-lubricating bearing 8 in the inner hole of the electromagnetic brake 4, the main lead screw sleeve disc 2 is inserted, and the limit plate 5 and the thrust washer 6 are installed for axial positioning. After the above structure is installed, the lead screw 13 is screwed in, the preloading spring 14 and the auxiliary lead screw sleeve disc 10 are installed. After adjusting the frictional torque to 0.5 - 0.6 N•m through a special tooling, the fastening positioning pin 11 is installed to complete the installation.

[0028] As Figure 3The following is a schematic diagram of the actual application structure of the present invention. The present invention is installed on the belt plate. When the carton gluing machine needs to adjust the position of a certain belt plate, the corresponding electromagnetic brake 4 brakes and locks the armature 9 and the lead screw sleeve disc. Since the main lead screw sleeve disc 2 and the auxiliary lead screw sleeve disc 10 are connected to the armature 9 through the connecting positioning pin 1 and the fastening positioning pin 11, rotating the lead screw 13 can move the belt plate; the electromagnetic brakes 4 on the remaining belt plates are not braked, so that the lead screw sleeve disc rotates following the lead screw 13 and the belt plate does not move. The pre-tightening spring 14 in the structure provides pressure to the lead screw sleeve disc to increase the friction force, ensuring that the lead screw sleeve disc stably rotates following the lead screw 13 when the electromagnetic brake 4 is not braked, and avoiding the crawling phenomenon of the belt plate. Thus, a set of lead screws 13 can be used to control the movement of multiple belt plates respectively.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
