Description

Technical Field

[0001] The utility model relates to the field of automatic box packing, in particular to an anti-collision carton opening device. Background Art

[0002] Cartons are a type of packaging product commonly used in the packaging field. Existing cartons are usually foldable, that is, they are formed by connecting multiple paperboards. When in use, they are assembled into a box body by folding and sealing. After the product is placed in the box body through the opening on the folded carton, the paperboard on the opening is folded and sealed to complete the packaging.

[0003] During automatic cartoning, in order to facilitate the material-taking device to place the product into the box, it is usually necessary to open the cardboard on the carton opening and fully expand the opening before packing. The prior art uses a swingable carton pressing head to automatically open the cardboard, but the cardboard on the carton opening can not only be folded toward the opening side, but also toward the side away from the opening. When the cardboard is folded toward the side away from the opening, the cardboard is easy to hit the pressing head during the transportation of the carton, thereby causing damage to the carton, affecting the progress of packing and causing unnecessary loss of the carton, thereby increasing costs. Utility Model Content

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a collision-proof carton opening device which is formed by connecting guide plates to form a guide area and a carton channel, thereby ensuring that the cardboard on the opening does not collide with the pressure plate assembly when the carton is conveyed toward the pressure plate assembly, thereby not causing damage to the carton and improving the packing efficiency.

[0005] The utility model adopts the following technical solutions:

[0006] A carton opening device comprises four groups of pressure plate assemblies and two guide plates, wherein the four groups of pressure plate assemblies are arranged in a rectangular shape so that the four groups of pressure plate assemblies are respectively located at the four corners of the carton, and the two guide plates are arranged in parallel and spaced apart so that a carton channel is formed between the two guide plates, and the pressure plate assembly comprises a carton pressing head which can swing between a standby position and a carton pressing position, and when the carton pressing head is located at the carton pressing position, the carton pressing head contacts and props up the cardboard on the carton opening, and the guide plate comprises a guiding part and a limiting part, wherein the guiding part is arranged at the front and rear ends of the limiting part, and the guiding part extends obliquely in a direction away from the carton channel, so that a guiding area with a gradually decreasing opening is formed between the guiding parts of the two guide plates.

[0007] Furthermore, the pressure plate assembly includes a carton pressing head, a swinging head, a connecting part and a swinging cylinder. The swinging head is connected to the connecting part through a pin shaft, and the swinging head can swing around the pin shaft. The carton pressing head is arranged on the swinging head, and the swinging cylinder is connected to and drives the swinging head to swing.

[0008] Furthermore, a rack is provided on the swing cylinder, a driving tooth is formed on the swing head, the rack is meshed with the driving tooth, the swing cylinder drives the rack to rise and fall, and drives the swing head to swing through the rack and the driving tooth.

[0009] Furthermore, the carton pressing head comprises two pressing plates, which are arranged to be inclined relative to each other so that there is an angle between the two pressing plates. When the carton pressing head is located at the box pressing position, the two pressing plates respectively contact and press against two adjacent paperboards on the carton.

[0010] Furthermore, a fixed seat is provided on the swing head, and two relatively inclined contact surfaces are provided on the fixed seat. The inclination angle of the contact surface is the same as the inclination angle of the pressure plate. The pressure plate is fixedly connected to the contact surface, so that the carton pressure head is fixedly set on the fixed seat.

[0011] Furthermore, the angle between the two pressing plates is greater than 45°, and the angle between the two pressing plates is less than 75°.

[0012] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:

[0013] First, the cardboard of the carton is pressed against by four pressing plate assemblies, and the cardboard is stretched outward to open the opening of the carton, which makes it easier to place the carton, and the carton is guided by the guide area formed by the guide plate. When the carton passes through the guide area, the cardboard that is expanded outward will be guided and gathered by the guide part to ensure that the cardboard does not collide with the pressing plate assembly and cause damage to the carton.

[0014] Second, the carton pressing head and the connecting part are connected through a swinging head, and the swinging head is driven to swing by a swinging cylinder, thereby driving the carton pressing head to swing. The swinging cylinder drives the swinging head to rotate through the meshing of the rack and the driving tooth. The structure is simple and compact. The carton pressing head is composed of two mutually inclined pressure plates, which can simultaneously support and open two adjacent cardboards on the carton, so that the opening on the carton can be expanded and more stable.

[0018] The present invention is further described below through specific implementation methods.

[0019] Reference Figure 1 and Figure 2 The utility model is a carton opening device, comprising four groups of pressing plate assemblies 1 and two guide plates 2. The four groups of pressing plate assemblies 1 are arranged in a rectangular shape so that the four groups of pressing plate assemblies 1 are respectively located at the four corners of the carton. The two guide plates 2 are arranged in parallel and spaced apart so that a carton channel is formed between the two guide plates 2. The pressing plate assembly 1 has a carton pressing head 10 that can swing between a standby position and a pressing position. When the carton pressing head 10 is located at the pressing position, the carton pressing head 10 contacts and props up the cardboard on the carton opening. The guide plate 2 comprises a guiding portion 20 and a limiting portion 21. The guiding portion 20 is arranged at the front and rear ends of the limiting portion 21. The guiding portion 20 extends obliquely in a direction away from the carton channel, so that a guiding area with a gradually decreasing opening is formed between the guiding portions 20 of the two guide plates 2.

[0020] The pressing plate assembly 1 includes a carton pressing head 10, a swinging head 11, a connecting part 12 and a swinging cylinder 13. The swinging head 11 is connected to the connecting part 12 through a pin shaft, and the swinging head 11 can swing around the pin shaft. The carton pressing head 10 is arranged on the swinging head 11, and the swinging cylinder 13 is connected to and drives the swinging head 11 to swing. A rack 14 is arranged on the swinging cylinder 13, and a driving tooth is formed on the swinging head 11. The rack 14 is meshed with the driving tooth. The swinging cylinder 13 drives the rack 14 to rise and fall, and drives the swinging head 11 to swing through the rack 14 and the driving tooth. The carton pressing head 10 includes two pressing plates 100, and the two pressing plates 100 are arranged to be inclined with respect to each other so that there is an angle between the two pressing plates 100. When the carton pressing head 10 is located at the box pressing position, the two pressing plates 100 respectively contact and press against two adjacent cardboards on the carton. The swing head 11 is provided with a fixed seat 15, and the fixed seat 15 is provided with two relatively inclined contact surfaces, and the inclination angle of the contact surfaces is the same as the inclination angle of the pressing plate 100. The pressing plate 100 is fixedly connected to the contact surfaces, so that the carton pressing head 10 is fixedly arranged on the fixed seat 15. The angle between the two pressing plates 100 is greater than 45°, and the angle between the two pressing plates 100 is less than 75°.

[0021] Continue to refer to Figure 1 and Figure 2When the utility model is used, during the transportation of the carton toward the carton opening device, the carton will first pass through the guide area formed between the two guide plates 2, and the guide area gradually decreases from the side away from the carton channel to the side of the carton channel. If the cardboard on the carton is not unfolded outward, the carton enters the carton channel after passing through the guide area. After the carton completely enters the carton channel, the swing cylinder 13 drives the swing head 11 to swing through the rack 14, so that the carton pressing head 10 swings to the box pressing position, and the pressing plate 100 contacts and stretches the cardboard during the swinging process, so that the opening of the carton is completely opened. If the cardboard of the carton is unfolded outward when entering the guide area, the cardboard will contact the guide part 20 on the guide plate 2 after the carton enters the guide area, and as the carton continues to move toward the carton channel, the cardboard is guided inward by the guide part 20 and finally restricted between the limiting parts 21, which can prevent the cardboard from colliding with the pressing plate assembly 1.
