Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically an automatic bonding device for cardboard box processing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly use three-layer or five-layer construction, while seven-layer construction is less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while corrugated paper is used for the core paper. The colors and textures of various types of paper are different. In the cardboard box processing industry, the bonding process is a crucial step.

[0003] While existing automatic cardboard box gluing devices can complete gluing, folding, and pressing operations, their pressing mechanism experiences significant pressure loss during the final pressing of the bonded joint due to the buffering and deformation of the cardboard material below (such as corrugated structure). This results in a deviation between the force applied to the bonded joint and the set force, causing the pressure deviation to be insufficient at the bonded joint, thus affecting the bonding strength and pressing quality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic gluing device for cardboard box processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic gluing device for cardboard box processing includes an automatic gluing machine and an internal conveying mechanism. A mounting rod is positioned above the automatic gluing machine, and a first roller pressing mechanism is located on the outer side of the mounting rod. The device also includes:

[0007] A pressing assembly is located on the outside of the mounting rod. The pressing assembly includes a clip sleeved on the outside of the mounting rod. A mounting plate is fixedly connected between the two clips. A first electric push rod is fixedly embedded on one side surface of the mounting plate. A second roller pressing mechanism is fixedly installed at one end of the first electric push rod. A support plate is movably provided below the second roller pressing mechanism.

[0008] The positioning component is located below the mounting plate.

[0009] Furthermore, two No. 2 electric push rods are fixedly embedded at both ends of one side surface of the mounting plate. A connecting plate is fixedly installed at one end of the No. 2 electric push rod, and a card seat is fixedly installed at both ends of the connecting plate.

[0010] Preferably, an electromagnet is fixedly embedded in the upper surface of the card holder.

[0011] Preferably, two clamping plates are fixedly installed at both ends of one side surface of the support plate, and the clamping plates are movably engaged with the corresponding clamping seats.

[0012] Furthermore, the positioning component includes:

[0013] A fixing sleeve is fixedly installed on one side surface of the card holder;

[0014] The rotating rod is rotatably connected inside the fixed sleeve;

[0015] The clamp is fixedly installed at one end of the outer surface of the rotating rod.

[0016] Preferably, the two card holders at the corresponding positions are rotatably connected to a drive shaft via a support ring on one side. Both ends of the drive shaft and the other end of the rotating rod are fixedly installed with a No. 1 bevel gear, and two adjacent No. 1 bevel gears are movably meshed and connected for transmission.

[0017] Preferably, a motor is fixedly installed on one side surface of the connecting plate, and two meshing bevel gears are fixedly installed on the output end of the motor and the outer surface of the transmission shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When the cardboard box is folded and passes the front end of the support plate, the card holder moves upward and separates from the cardboard. At this time, the front end of the support plate is inserted into the inside of the cardboard box to support it. After the cardboard box passes the cardboard, the card holder at that point moves downward, and the electromagnet is energized to work, attracting the cardboard into the inside of the card holder and fixing the support plate. In conjunction with the pressing of the No. 2 roller pressing mechanism, the adhesive joint is pressed and reinforced, reducing the buffering and deformation effects of the cardboard material below, maintaining a stable force at the pressing joint, and improving the bonding strength and pressing quality.

[0020] 2. When the motor runs, the transmission shaft rotates through the transmission of the second bevel gear, and the rotating rod rotates through the transmission of the first bevel gear, which drives the clamping plate to rotate and press against the clamping plate. This causes the clamping plate to move the support plate and restrict it to a specific position, making it easier to engage with the clamping seat and improving the engagement accuracy of the clamping plate and the clamping seat.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 In this embodiment of the present invention, an automatic gluing device for carton processing includes an automatic gluing machine 1 and a conveying mechanism 101 inside it. An installation rod 102 is provided above the automatic gluing machine 1. A first roller pressing mechanism 103 is provided on the outside of the installation rod 102. The device also includes a pressing assembly 2, which is provided on the outside of the installation rod 102. The pressing assembly 2 includes a clip 201 sleeved on the outside of the installation rod 102. An installation plate 202 is fixedly connected between the two clips 201. A first electric push rod 203 is fixedly embedded on one side surface of the installation plate 202. A second roller pressing mechanism 204 is fixedly installed at one end of the first electric push rod 203. The first electric push rod 203 extends and retracts to adjust the position of the second roller pressing mechanism 204 and control the pressure applied to the gluing area. A support plate 205 is movably provided below the second roller pressing mechanism 204. A positioning assembly 3 is provided below the installation plate 202.

[0029] Specifically, after the carton is folded by the folding mechanism, the glued parts of the carton are connected together and conveyed by the conveying mechanism 101. The first roller pressing mechanism 103 presses from above the carton to maintain the stability of the carton after folding. At this time, the support plate 205 is inserted into the carton to support from below the glued parts. Then, the second roller pressing mechanism 204 presses the glued parts of the carton to improve the bonding strength of the glued parts.

[0030] Example 1

[0031] like Figure 1-4 As shown, in this embodiment, two second-generation electric push rods 207 are fixedly embedded at both ends of one side surface of the mounting plate 202. A connecting plate 208 is fixedly installed at one end of the second-generation electric push rod 207, and a retaining seat 209 is fixedly installed at both ends of the connecting plate 208. The front and rear ends of the support plate 205 are fixed by the two sets of retaining seats 209 respectively, maintaining the angle of the support plate 205, preventing it from tilting, and improving the connection firmness. An electromagnet 308 is fixedly embedded in the upper surface of the retaining seat 209. Two retaining plates 206 are fixedly installed at both ends of one side surface of the support plate 205, and the retaining plates 206 are movably engaged with the retaining seats 209 at the corresponding positions.

[0032] In this embodiment, when the carton passes the front end of the support plate 205 after being folded, the electromagnet 308 at its front end is de-energized, the second electric push rod 207 retracts, and drives the card holder 209 to move upward, separating it from the card plate 206. At this time, the front end of the support plate 205 is inserted into the carton to support it. After the carton passes the card plate 206, the card holder 209 at that location moves downward, the electromagnet 308 is energized, and the card plate 206 is attracted to the inside of the card holder 209, fixing the support plate 205. With the compression of the second roller pressing mechanism 204, the adhesive joint is compressed and reinforced, reducing the buffering and deformation effects of the carton material below, maintaining a stable force at the pressing joint, and improving the adhesion and pressing quality. After pressing, similarly, the electromagnet 308 at the rear end of the support plate 205 is de-energized, the card holder 209 separates from the card plate 206, and the carton passes through easily.

[0033] Example 2

[0034] Based on Embodiment 1, in order to solve the problem that the engagement accuracy between the card plate 206 and the card holder 209 is not high when the support plate 205 is offset.

[0035] like Figure 5 As shown, in this embodiment, the positioning component 3 includes: a fixed sleeve 301 fixedly installed on one side surface of the card holder 209, a rotating rod 302 rotatably connected to the inside of the fixed sleeve 301, and a clamping plate 303 fixedly installed at one end of the outer surface of the rotating rod 302.

[0036] In practice, the rotating rod 302 drives the clamping plate 303 to flip downwards and press against the clamping plate 206, so that the clamping plate 206 drives the support plate 205 to be restricted in a specific position, which facilitates engagement with the clamping seat 209 and improves the engagement accuracy of the clamping plate 206 and the clamping seat 209.

[0037] like Figure 5As shown, in this embodiment, the two card holders 209 at corresponding positions are rotatably connected to a drive shaft 304 via a support ring. Both ends of the drive shaft 304 and the other end of the rotating rod 302 are fixedly installed with a first bevel gear 305. The two adjacent first bevel gears 305 are movably meshed and connected for transmission. A motor 306 is fixedly installed on one side of the connecting plate 208. The output end of the motor 306 and the outer surface of the drive shaft 304 are fixedly installed with two second bevel gears 307 that are meshed and connected for transmission.

[0038] In practice, the motor 306 operates, and through the transmission of the second bevel gear 307, the transmission shaft 304 rotates. Through the transmission of the first bevel gear 305, the rotating rod 302 rotates, driving the clamping plate 303 to rotate, thus providing power for the rotation of the clamping plate 303.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
