Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and specifically to a clamping device for cardboard box processing. Background Technology

[0002] Cardboard box processing is a multi-step process designed to transform cardboard materials into a variety of boxes to meet different packaging and shipping needs.

[0003] In the production of cardboard boxes, multiple pieces of cardboard need to be moved and continuously added to semi-automatic equipment (for example, printing, hot stamping, etc.). In the existing technology, small-scale factories generally use manual handling and lifting to flexibly add cardboard to semi-automatic equipment.

[0004] However, continuously handling cardboard without tools can not only injure workers' hands, but also, since cardboard is usually corrugated and leans against the equipment, frequently lifting it by manually pinching the edges may deform or damage the cardboard due to excessive force, affecting subsequent processing. Utility Model Content

[0005] In view of this, the present invention provides a clamping device for cardboard box processing. The device can clamp multiple pieces of cardboard by means of a fixed frame and multiple first nuts, and multiple second nuts, and by means of multiple adjusting cranks. When lifting, the two clamping plates can be controlled to move towards each other to clamp multiple pieces of cardboard. When releasing, the multiple pieces of cardboard can be put down. Therefore, it is not necessary for the staff to frequently lift multiple pieces of cardboard manually, and the edges of the cardboard are avoided from being deformed or damaged by frequent lifting.

[0006] To solve the above-mentioned technical problems, this utility model provides a clamping device for carton processing, including a fixed frame, on both sides of the fixed frame, a first nut is symmetrically arranged, that is, a first nut is symmetrically welded on each side of the fixed frame, clamping plates are symmetrically arranged inside the fixed frame, the clamping plates are supported and their positions are adjusted by adjusting the crank, and a second nut is symmetrically arranged on one side of the vertical surface of each clamping plate, that is, a second nut is symmetrically welded on the opposite vertical surfaces of the two clamping plates;

[0007] Each first nut and each second nut are connected to a fixing bolt by thread engagement. An adjusting crank is provided on the outer wall of each pair of fixing bolts on the same side. Each adjusting crank has a circular through hole corresponding to the position of the two fixing bolts. The two fixing bolts pass through the circular through hole and are connected to the first nut and the second nut respectively by thread engagement.

[0008] Each pair of corresponding adjusting cranks must be staggered, meaning that the first nut symmetrically arranged on one side of the fixing frame and the second nut symmetrically arranged on one side of one of the clamping plates must both protrude outward by the thickness of an adjusting crank, so that each pair of corresponding adjusting cranks are staggered.

[0009] Each pair of adjusting cranks connected to the same clamping plate is rotatably connected to a handle via a bearing. The rotation of the handle makes it easier to lift the adjusting cranks and the components below them without causing friction to the operator's palms.

[0010] Both grips have an anti-slip layer on their outer side walls. The anti-slip layer can be made of rubber and is fixedly attached to the outer side walls of the grips by a solvent bonding method.

[0011] The fixing bolt is set as a semi-threaded bolt, and the smooth end of the semi-threaded bolt can be equal to the thickness of the adjusting crank.

[0012] Sponges are provided on the opposing surfaces of the two clamping plates, and the sponges are fixedly connected to the clamping plates by a sol-gel bonding method.

[0013] The sponge is made of polyurethane, which has good resilience and can return to its original shape after being frequently clamped between multiple pieces of cardboard.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. By using a fixed frame and multiple first nuts to hold the clamping plates and multiple second nuts, and with the connection of multiple adjusting cranks, the clamping plates can be controlled to move towards each other to clamp multiple pieces of cardboard when lifting, and can be put down when releasing. Therefore, it is not necessary for staff to frequently lift multiple pieces of cardboard manually, avoiding deformation or damage to the cardboard caused by frequently picking up the edges of multiple pieces of cardboard.

[0016] 2. The added sponge further enhances the protection of the cardboard, thus preventing damage when clamping multiple pieces of cardboard.

[0017] 3. By setting the fixing bolts as half-threaded bolts, the adjusting crank will not be unable to rotate even if the fixing bolts are tightened, thus reducing the difficulty of installation. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] The effect of the solution in claim 1 is as follows: Figure 1 , 3 As shown in Figure 4: A clamping device for cardboard box processing includes a fixed frame 101. The fixed frame 101 is provided to support the various components thereon, and the inner sidewall of the fixed frame 101 can limit the top of the cardboard. First nuts 103 are symmetrically arranged on both vertical surfaces of the fixed frame 101. The first nuts 103 are provided to cooperate with the second nuts 108 to support the adjusting crank 104. When the adjusting crank 104 rotates to adjust the position of the clamping plate 102, the fixing bolts 105 ensure that the adjusting crank 104 will not move during rotation. That is, first nuts 103 are symmetrically welded on each vertical surface of the fixed frame 101, thereby making its connection structure more stable.

[0025] During manufacturing, the first nut 103 is welded to the fixing frame 101, and the tightness of the welding of the first nut 103 is checked. It is also necessary to note that the two first nuts 103 on one side of the vertical surface protrude outward from the fixing frame 101 by the thickness of the adjusting crank 104 compared to the two first nuts 103 on the other side of the vertical surface.

[0026] The fixing frame 101 is symmetrically equipped with clamping plates 102. The clamping plates 102 are arranged so that when the two clamping plates 102 move towards each other, they can clamp multiple pieces of cardboard. When the two clamping plates 102 move away from each other, they can prevent multiple pieces of cardboard from loosening and make it easier to remove multiple pieces of cardboard. The clamping plates 102 are supported and their positions are adjusted by adjusting cranks 104. The position of the clamping plates 102 can be adjusted by moving the adjusting cranks 104. The second nuts 108 are symmetrically arranged on one vertical surface of each clamping plate 102. The second nuts 108 are arranged so that the clamping plates 102 can move with the adjustment cranks 104 and can further support the adjustment cranks 104. That is, the second nuts 108 are symmetrically welded on the opposite vertical surfaces of the two clamping plates 102, so that their connection structure is more stable.

[0027] Weld the second nut 108 onto the corresponding clamping plate 102 and check the tightness of the welding of the second nut 108. Also, the two second nuts 108 on one of the clamping plates 102 need to protrude outward from the clamping plate 102 by the thickness of an adjusting crank 104, so that every two corresponding adjusting cranks 104 are staggered.

[0028] Each first nut 103 and each second nut 108 is connected to a fixing bolt 105 via a threaded connection. The fixing nuts allow each adjusting crank 104 to be supported by the first nut 103 and the second nut 108, and allow rotation through the circular hole in the adjusting crank 104 onto the fixing bolt 105. If the fixing bolt 105 is a standard bolt, the diameter of the circular hole must be 1-3 mm longer than the diameter of the fixing bolt 105 to prevent jamming during displacement of the adjusting crank 104. An adjusting crank 104 is located on the outer wall of every two fixing bolts 105 on the same side. The four adjusting cranks 104 can be simultaneously adjusted. When the four adjusting cranks 104 are lifted, they move upwards simultaneously, causing the two clamping plates 102 to move towards each other. When they are released, the four adjusting cranks 104 will fall due to gravity, allowing the two clamping plates 102 to move away from each other. When using ordinary bolts as fixing bolts 105, the fixing bolts 105 cannot be fully tightened, and a certain gap must be left so that the adjusting cranks 104 can move. Each adjusting crank 104 has a circular through hole corresponding to the position of two fixing bolts 105. After the two fixing bolts 105 pass through the circular through hole, they are connected to the first nut 103 and the second nut 108 respectively through threaded engagement, so that the adjusting crank 104 can be supported in it.

[0029] During installation, pass the fixing bolt 105 through the circular hole on the adjusting crank 104, and then connect the fixing bolt 105 to the corresponding first nut 103 and second nut 108 respectively, without tightening them. After installation, connect the two clamping plates 102 to the fixing frame 101. Check to ensure that the clamping plates 102 will not fall off the fixing frame 101, and adjust the tightness of the fixing bolt 105 to ensure that the adjusting crank 104 can move stably when lifting multiple adjusting cranks 104, avoiding jamming.

[0030] Each pair of corresponding adjusting cranks 104 needs to be staggered. That is, the first nut 103 symmetrically arranged on one side of the fixing frame 101 and the second nut 108 symmetrically arranged on one side of one of the clamping plates 102 both need to protrude outward by the thickness of one adjusting crank 104. This ensures that each pair of corresponding adjusting cranks 104 are staggered, thus avoiding collisions between each pair of corresponding adjusting cranks 104 and allowing the four adjusting cranks 104 to be adjusted synchronously, preventing damage to the cardboard caused by the separate movement of the two clamping plates 102.

[0031] The effect of the solution in claim 2 is as follows: Figure 1 , 2 As shown: Each pair of adjusting cranks 104 connected to the same clamping plate 102 is rotatably connected to a handle 107 via a bearing. The handle 107 allows the two adjusting cranks 104 on different sides to be connected, making it easier for the operator to pick up and put down the cranks. This further improves the control effect of the adjusting cranks 104. The rotation of the handle 107 makes it easier to lift the adjusting cranks 104 and their components by the two handles 107 without causing friction to the operator's palm.

[0032] The effect of the solution in claim 3 is as follows: Figure 1 , 2 As shown: Both outer walls of the two handles 107 are provided with anti-slip layers. The anti-slip layers prevent the staff from slipping when picking up the cardboard, thereby improving safety and preventing the cardboard from falling to the ground and being damaged. The anti-slip layers can be made of rubber, which can increase friction without abrading the staff and causing injury, thus protecting the staff. They are fixed to the outer walls of the handles 107 by adhesive bonding, making the connection structure more stable.

[0033] The effect of the solution in claim 4 is as follows: Figure 2 , 3As shown: The fixing bolt 105 is a half-thread bolt. The half-thread bolt makes the part connecting to the adjusting crank 104 smooth, so that the adjusting crank 104 will not get stuck when it needs to be adjusted and rotated. The smooth end of the half-thread bolt can be equal to the thickness of the adjusting crank 104, so that it can cooperate with the first nut 103 or the second nut 108 to the maximum extent and will not lock the adjusting crank 104. Even if the fixing bolt 105 is tightened, the adjusting crank 104 will not be unable to rotate. Therefore, the installation difficulty can be further reduced.

[0034] The effect of the solution in claim 5 is as follows: Figure 1 As shown: Sponges 106 are provided on the opposing surfaces of the two clamping plates 102. The sponges 106 are provided to further prevent damage to multiple pieces of cardboard when the two clamping plates 102 are clamped. The sponges 106 are fixedly connected to the clamping plates 102 by means of sol-gel bonding, thereby making the connection structure more stable.

[0035] The effect of the solution in claim 6 is as follows: Figure 1 As shown: Sponge 106 is made of polyurethane. Due to its good resilience, it can return to its original shape after being frequently clamped by multiple pieces of cardboard. It also has high wear resistance, which can improve service life, extend service time, and save costs.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment 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 protection scope of this utility model.
