Description

Technical Field

[0001] This utility model belongs to the field of paper box forming technology, and specifically relates to a paper box forming device. Background Technology

[0002] In the process of processing cardboard boxes, a forming device is needed to press and shape the cardboard material. While existing cardboard box forming devices can meet the basic requirements for pressing cardboard boxes, their clamping structures typically rely solely on telescopic mechanisms for translational adjustment, lacking auxiliary support structures. This results in the clamping and telescopic structures directly bearing the downward pressure during the pressing process, making them prone to deformation and damage. Consequently, they cannot fully meet user needs.

[0003] For example, the utility model patent with announcement number CN218615617U discloses a paper box forming machine. In the technical solution of this patent document, the clamping plate is adjusted by the clamping cylinder to clamp the paper box material, and the forming pressure block is adjusted by the pushing cylinder to press the paper box material. As a result, the clamping cylinder and the clamping plate will directly bear the downward pressure force, which will easily cause the clamping cylinder and the clamping plate to deform and be damaged. Therefore, the clamping cylinder and the clamping plate need to be replaced frequently. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a paper box forming device that not only meets the basic requirements for forming and pressing paper boxes, but also prevents the clamping plate and corresponding adjustment structure from being easily deformed and damaged.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a paper box forming device, including a base, a frame is set on the base via support legs, a first telescopic push rod is set on each of the four sides of the frame, an L-shaped clamping plate is set on the output shaft of the first telescopic push rod, a support cylinder is also set on each of the four sides of the frame, a support rod is set on the clamping plate to be inserted into the support cylinder, a U-shaped mounting frame is also set on the top of the frame, a second telescopic push rod is vertically set on the top of the mounting frame, and a forming groove with a top opening is set on the output shaft of the second telescopic push rod.

[0006] As a further improvement of this utility model, the top of the mounting bracket is provided with a guide slot located at the side end of the second telescopic push rod, and a guide plate that is inserted into the guide slot is provided on the forming groove.

[0007] As a further improvement of this utility model, a third telescopic push rod is also provided laterally on the side end of the mounting bracket. A protective slot is provided on the output shaft of the third telescopic push rod, and a protective plate that can engage with the anti-slip slot is provided on the side end of the guide plate.

[0008] As a further improvement of this utility model, a connecting slot is provided on the side of the mounting bracket, and a connecting plate is provided on the side of the protective slot to be inserted into the connecting slot. Through the insertion and cooperation of the connecting slot and the connecting plate, the protective slot can move horizontally stably, and the third telescopic push rod can be easily deformed and damaged due to accidental vertical force on the protective slot.

[0009] As a further improvement of this utility model, a collection trough is also provided on the base below the frame. The collection trough allows for convenient collection and processing of the cardboard boxes that fall after pressing and forming.

[0010] As a further improvement of this utility model, the base is provided with a placement groove that engages with the collection slot. The placement groove allows for flexible fixing of the collection slot to the base and precise placement of the placement slot.

[0011] As a further improvement of this utility model, a handle is also provided on the collection tank. The handle allows for easy movement of the collection tank, facilitating the flexible fixing of the collection tank to the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by setting a support rod on the clamping plate and engaging it with the support cylinder on the side of the frame, the clamping plate and the first telescopic push rod are effectively prevented from deforming or being damaged by external forces, thus improving the service life and reliability of the equipment.

[0014] Secondly, a guide slot is set at the top of the mounting frame, which cooperates with the guide plate on the forming groove to ensure that the forming groove maintains a precise linear movement when moving vertically, thereby improving the pressing accuracy; and effectively preventing the second telescopic push rod from being easily damaged by terrain deformation; and the groove-shaped pressing structure not only ensures the basic effect of pressing and forming, but also reduces the weight of the forming structure.

[0015] Thirdly, the interlocking of the protective slot and the protective plate prevents the forming groove from accidentally falling and injuring the user's hand during the feeding process of placing the paper box material to be pressed onto the clamping plate, thus significantly improving the stability and safety of the device.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 3 As shown, a cardboard box forming apparatus includes a base 101. Support legs 112 are fixedly connected to the four corners of the base 101. A frame 102 is fixedly connected to the four support legs 112. First telescopic push rods 103 are fixedly connected to the four side ends of the frame 102. The fixed ends of the first telescopic push rods 103 are fixedly connected to the side ends of the frame 102. The output shafts of the first telescopic push rods 103 pass through the side ends of the frame 102. L-shaped clamping plates 104 are fixedly connected to the output shafts of the first telescopic push rods 103. The four side ends of the frame 102... Supporting inserts 105 are also connected through and fixedly attached to the clamping plate 104. Supporting rods 106 that are inserted into the supporting inserts 105 are fixedly attached to the clamping plate 104. A U-shaped mounting bracket 107 is also fixedly attached to the top of the frame 102. A second telescopic push rod 108 is vertically fixedly attached to the top of the mounting bracket 107. The fixed end of the second telescopic push rod 108 is fixedly attached to the top of the mounting bracket 107. The output shaft of the second telescopic push rod 108 passes downward through the top of the mounting bracket 107. A forming groove 109 with a top opening is provided on the output shaft of the second telescopic push rod 108.

[0024] The output shafts of the four first telescopic push rods 103 are extended and retracted to adjust the horizontal position of the clamping plate 104, so that the position of the clamping plate 104 matches the size of the paper box material to be pressed and formed. Then, the paper box material to be pressed and formed can be placed on the four clamping plates 104. The lateral insertion of the support rod 106 and the support cylinder 105 can enhance the stability of the clamping plate 104 and prevent the clamping plate 104 and the first telescopic push rods 103 from being deformed or damaged by external forces.

[0025] Then, the output axis of the second telescopic push rod 108 can be driven to extend downward by a certain length, causing the forming groove 109 to move downward. Through the cooperation of the pressure groove and the four clamping plates 104, the paper box material is pressed.

[0026] Then, the output shaft of the second telescopic push rod 108 can be driven to shorten upward by a certain length, causing the forming groove 109 to reset upward, and the output shaft of the first telescopic push rod 103 can be driven to shorten laterally by a certain length, releasing the support of the cardboard box, releasing the cardboard box material, and causing the cardboard box to fall under the action of gravity.

[0027] This completes the pressing process for a cardboard box. Afterward, simply repeat the above process to continue pressing and shaping the cardboard box material.

[0028] According to another embodiment of the present invention, such as Figure 1 As shown, the top of the mounting bracket 107 is fixedly connected to and has a guide slot 110 located at the side end of the second telescopic push rod 108. A guide plate 111 that engages with the guide slot 110 is fixedly connected to the forming groove 109. The guide plate 111 cooperates with the guide slot 110 at the top of the mounting bracket 107 to ensure that the groove maintains precise linear movement when moving vertically, thereby improving the pressing accuracy.

[0029] According to another embodiment of the present invention, such as Figure 4 As shown, a third telescopic push rod 201 is also laterally fixed to the side end of the mounting bracket 107. The fixed end of the third telescopic push rod 201 is fixed to the side end of the mounting bracket 107. The output shaft of the third telescopic push rod 201 passes laterally through the side end of the mounting bracket 107. A protective slot 202 is fixed to the output shaft of the third telescopic push rod 201. A protective plate 203 that can engage with the anti-slip slot is fixed to the side end of the guide plate 111.

[0030] After the forming groove 109 is reset upward, the output shaft of the third telescopic push rod 201 can be driven to extend by a certain length, so that the protective slot 202 and the protective plate 203 are engaged and cooperated to protect the protective plate 203 and the corresponding guide plate 111 and forming groove 109 from accidental fall, thereby preventing the forming groove 109 from falling accidentally during the feeding process of placing the paper box material on the clamping plate 104, thus protecting the user's hand safety.

[0031] After the material is loaded, when it is necessary to drive the forming groove 109 to move downward, simply drive the output shaft of the third telescopic push rod 201 to shorten by a certain length, thereby driving the protective slot 202 to separate from the protective plate 203, and releasing the limit on the guide plate 111 and the pressing groove.

[0032] According to another embodiment of the present invention, such as Figure 4 As shown, the side end of the mounting bracket 107 is also laterally connected to a connecting slot 204, and the side end of the protective slot 202 is also fixedly connected to a connecting plate 205 that plugs into the connecting slot 204. Through the lateral insertion and cooperation between the connecting plate 205 and the connecting slot 204, the sturdiness of the protective slot 202 can be ensured, and the third telescopic push rod 201 can be prevented from being easily deformed and damaged.

[0033] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, a collection trough 301 located below the frame 102 is also placed on the base 101. After the collection trough 301 is placed on the base 101, the formed cardboard box will automatically fall into the collection trough 301, thus facilitating the collection and processing of the cardboard box.

[0034] According to another embodiment of the present invention, such as Figure 3 As shown, the base 101 is provided with a placement groove 302 that engages with the collection groove 301. By simply engaging and fixing the collection groove 301 with the placement groove 302, the collection groove 301 and the base 101 can be flexibly fixed together, and the placement groove can be accurately placed.

[0035] According to another embodiment of the present invention, such as Figure 2 As shown, a handle 303 is also fixedly connected to the collection tank 301. The handle 303 is U-shaped. The collection tank 301 can be moved easily by the handle 303, and the collection tank 301 can be flexibly fixed to the base 101.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
