[0001] The utility model belongs to the technical field of clamping tool, specifically relates to a ton bag clamping device. BACKGROUND

[0009] Preferably, the sliding assembly includes a sliding plate and a sliding rail, the clamping piece is connected to the sliding plate, the sliding plate is slidingly connected to the sliding rail, and the sliding rail moves on the sliding plate.

[0010] Further preferably, a vertical plate is vertically connected to the sliding plate, and the vertical plate is connected with the spring on the side facing the clamping sheet, and the vertical plate is used to fix the spring on the sliding plate to ensure the stability of the spring to the clamping sheet.

[0011] Further preferably, a groove is arranged on the surface of the sliding rail, and the width of the groove is consistent with the width of the sliding plate, so as to ensure the smooth sliding of the sliding plate on the sliding rail, avoid the shaking and deviation in the sliding process, and further improve the accuracy and stability of clamping.

[0012] Preferably, a positioning block is arranged between the spring and the connecting assembly.

[0013] Further preferably, the positioning block comprises a plurality of bolts and a block body, a through hole is arranged in the block body, the connecting assembly is arranged in the through hole on the side facing the clamping cylinder, and the spring is arranged in the through hole on the side facing the clamping body.

[0014] Preferably, the connecting assembly comprises a limiting piece, a long rod and a bearing, the limiting piece is connected to one end of the positioning block, the limiting piece is connected with the bearing through the long rod, and the bearing is connected with the clamping cylinder at the end away from the long rod.

[0015] A baffle is arranged on the connecting assembly, and a through hole is arranged in the baffle, and the long rod is arranged in the through hole.

[0016] The connecting assembly helps to adjust the stable connection and transmission between the components of the adjusting assembly, so as to ensure that the driving force of the clamping cylinder can be accurately transmitted to the clamping sheet, thereby realizing effective clamping.

[0017] Further preferably, one end of the baffle is slidingly connected with the sliding assembly, so as to ensure that the driving force of the clamping cylinder is applied to the spring through the connecting assembly in a specified direction, and the accuracy of the clamping force of the clamping device is improved.

[0018] Preferably, a dust suction cover is arranged in the clamping body, and the dust suction cover is connected with a dust suction pipeline.

[0023] Preferably, a sealing strip is attached to the inner side of the clamping piece.

[0024] The power transmission principle of the clamping device: the clamping cylinder is the main power source of the clamping device. When the electromagnetic valve receives a signal, it controls the extension and retraction of the clamping cylinder. The extension or retraction of the cylinder generates a pushing or pulling force, which is the basis of the entire clamping action. The long rod serves as a key component connecting the cylinder and the spring, and plays a transmission role. When the cylinder is extended, it pushes the limiting piece and the positioning block through the long rod, and then compresses the spring, so that the clamping piece moves to the center to clamp the ton bag. Conversely, when the cylinder is shortened, the spring force is released through the long rod and the limiting piece, so that the clamping piece is loosened. The limiting piece and the positioning block jointly play the role of guiding and positioning. The positioning block is fixed at one end of the spring, and the limiting piece is connected with the long rod. In this way, when the cylinder acts, the long rod pushes the positioning block and the spring through the limiting piece, ensuring that the direction of power transmission is accurate. At the same time, the design of the limiting piece and the positioning block also limits the excessive deformation of the spring, maintaining the stability of the clamping force. The spring is an important energy storage element in the clamping device. When the cylinder is extended, the spring is compressed and stores energy. When the cylinder is shortened, the spring releases energy and pushes the clamping piece to loosen. The stiffness and pre-tightening force of the spring determine the size and range of the clamping force. By adjusting the stiffness and pre-tightening force of the spring, the clamping force and range can be accurately controlled.

[0025] Adjustment of clamping force: the clamping force is mainly determined by the stiffness and pre-tightening force of the spring. By replacing springs with different stiffness or adjusting the pre-tightening force, the size of the clamping force can be changed. In addition, the pushing force of the cylinder can also be adjusted by the control of the electromagnetic valve, so as to further adjust the clamping force.

[0026] Adjustment of clamping range: the clamping range is mainly determined by the length of the long rod and the extension stroke of the cylinder. By adjusting the length of the long rod or the extension stroke of the cylinder, the distance between the clamping pieces can be changed, so as to clamp ton bags of different sizes. At the same time, the design of the limiting piece and the positioning block also ensures the stability and accuracy of the clamping range.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The utility model provides a kind of ton bag clamping device, including clamping body, clamping piece and adjusting assembly, wherein, the setting of sliding assembly realizes the adjustment of clamping piece clamping range, so that clamping device can adapt to ton bag of different sizes;Spring is used as elastic element, and it plays the role of buffering and restoring force during clamping process, when clamping cylinder provides clamping force, spring will be compressed;When clamping force is released, spring will push clamping piece back to initial position, thereby adjusting initial tension and restoring force in clamping process, so as to realize the preliminary adjustment of clamping force;Connecting assembly connects spring and clamping cylinder into a whole, to ensure that they can work cooperatively;Clamping cylinder is the main power source of providing clamping force, by controlling the working pressure or extension length of clamping cylinder, the size of clamping force can be accurately adjusted, in conclusion, by the cooperation of sliding assembly, spring and clamping cylinder, the technical problem of unadjustable clamping force and range of clamping device in prior art is solved.

[0029] Further, by setting the positioning block to limit the movement range of the sliding plate and the clamping piece, it is ensured that they will not exceed the predetermined position during clamping, by adjusting the position or number of the positioning block, the stroke of the clamping piece can be changed, thereby affecting the size of the clamping force.

[0030] Further, in the connecting assembly, the limiting piece is connected with the positioning block, ensuring the stability of the spring during elongation or shortening, preventing excessive deformation or deviation of the spring from the predetermined track, thereby ensuring accurate control of the clamping force;The long rod serves as a bridge connecting the limiting piece and the bearing, not only transmitting the power of the clamping cylinder, but also adjusting the relative position between the spring and the clamping cylinder through its length, thereby affecting the clamping range and force, the design of the long rod makes the adjustment of clamping force more flexible and accurate;The bearing is connected to the other end of the long rod and connected with the clamping cylinder. The presence of the bearing allows smooth rotation of the long rod when subjected to the thrust of the cylinder, reducing friction and wear, improving the efficiency and life of the entire adjusting assembly. At the same time, the bearing also plays a supporting and positioning role, ensuring the stability and accuracy of the clamping action;The baffle is provided with a through hole through which the long rod is arranged, which fixes the position of the long rod and prevents lateral movement or falling of the long rod during the force process. This further enhances the stability and reliability of the adjusting assembly, ensuring that the driving force of the clamping cylinder is applied to the spring in the specified direction through the connecting assembly, improving the accuracy of the clamping force of the clamping device.

[0031] Further, the sliding assembly mainly consists of a sliding plate and a sliding rail, and the sliding connection between them allows the clamping piece to move in the horizontal direction. This design allows the clamping device to adapt to ton bags of different sizes and ensures that the clamping piece is evenly distributed on both sides of the ton bag.

[0032] Further, the design of the dust cover and the dust suction pipeline allows dust generated during the clamping of the ton bag to be collected and treated at the same time, avoiding pollution of the environment and the operator, and improving the cleanliness and safety of the working environment.

[0033] Further, the dust absorption ports inside the dust cover can more effectively collect dust, improve the dust suction efficiency, and ensure the cleanliness of the working environment.

[0034] Further, the two dust suction pipelines arranged symmetrically can ensure the uniformity and efficiency of dust collection, avoid dust accumulation on one side, and improve the dust suction effect.

[0035] Further, the design of the dust collection port allows the collected dust to be easily discharged or treated, avoiding dust accumulation inside the device and maintaining the cleanliness and efficient operation of the device.

[0036] Further, the bracket provided on the clamping body provides stable support for the adjustment of the clamping body, and allows the adjustment assembly and the fixing member to be firmly connected together, ensuring the stability and reliability of the entire device.

[0037] Further, the sealing strip attached to the inner side of the clamping piece can ensure that a good seal is formed between the clamping piece and the ton bag during the clamping of the ton bag, preventing dust leakage and improving the dust suction effect, while protecting the clamping piece from wear and tear.
