Description

Technical Field

[0001] This utility model relates to the field of tableting machine tools, and in particular to a special wrench for disassembling the middle mold of a tableting machine in the catalyst industry. Background Technology

[0002] The final molding of the hydrogenation catalyst involves pressing the material into the required shape and size using a pelletizing machine. However, after prolonged operation, the molds of the pelletizing machine wear down, resulting in finished products that do not meet usage standards. Therefore, the molds need to be replaced or cleaned periodically. The original manufacturer's method for disassembling the mold is to first remove the upper and lower punches, then use the provided tools to tap the middle mold upwards through the lower punch hole to push it out of the large plate. This method is extremely slow, requiring constant tapping of each hole with the tool in a very confined space, increasing the risk of hand injury.

[0003] When disassembling the middle mold of the tableting machine, personnel are prone to scratches; it can cause secondary damage to the equipment, wear and tear on the mold, and reduce efficiency, thus affecting catalyst production efficiency.

[0004] A detachable mold automatic ejection device is disclosed in Chinese patent document CN216885378U. This device includes a housing, with a rotating drive source fixedly connected to the inner wall of the housing. A rotating shaft 1 and a rotating shaft 2 are rotatably connected to the inner wall of the housing. A gear 1 is fixedly connected to the drive unit of the rotating drive source. Gears 2 and 3 are fixedly connected to the surfaces of rotating shafts 1 and 2, respectively, with the tooth surfaces of gear 1 meshing with the tooth surfaces of gears 2 and 3. Incomplete gears 1 and 2 are fixedly connected to the surfaces of rotating shafts 1 and 2, respectively. A mold is detachably connected to the upper surface of the housing, and a mold cavity is formed inside the mold. This invention features a double-sided rack plate that drives a horizontal plate to move upwards, achieving the effect of automatically ejecting materials for easy worker pickup. It solves the problem of materials stuck in the mold cavity, leading to low work efficiency and low finished product output. However, this detachable mold automatic ejection device is located inside the housing, resulting in a complex structure.

[0005] A mold insert removal mechanism and method are disclosed in Chinese patent document CN105128211B. The mold insert has a fixing pin hole for fixing the insert and an ejector pin hole for ejecting the insert. A pin is installed in the fixing pin hole and can be inserted into the ejector pin hole. The removal method includes the following steps: with the mold in the open state; removing the pin from the fixing pin hole; inserting the removed pin into the ejector pin hole, the inner end of the pin ejects the insert; then removing the ejected insert from the mold; and placing the removed insert into an insert storage box on the mold. Insert removal and replacement are simple, the mold does not need to be removed from the machine, saving replacement time, improving production efficiency, and reducing costs. However, this mold insert removal mechanism and method are not suitable for mold equipment that requires disassembly of the intermediate mold.

[0006] To address the shortcomings of the existing technology, providing a special wrench for disassembling the mold in a catalyst pelletizing machine is a problem worthy of research. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of low efficiency and its impact on catalyst production efficiency, and to provide a special wrench for disassembling the middle mold of a catalyst tableting machine, thereby achieving the technical effect of improving the disassembly efficiency of the middle mold of the catalyst tableting machine.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A special wrench for disassembling the intermediate mold of a catalyst tableting machine includes a wrench handle, a support rod fixedly connected to one side of the wrench handle, a bent part fixedly connected to the end of the support rod, and a pry bar fixedly connected to the end of the bent part. It forms a basic tool shape specifically for ejection operations in narrow spaces. Through the lever principle, the downward pressing action at the handle is converted into an upward ejection force at the pry bar, avoiding the inefficiency and safety hazards of traditional knocking methods, and providing a basic tool structure for solving the problem of intermediate mold disassembly.

[0010] Optionally, the support rod is fixedly connected to the middle of one side of the wrench handle. The length of the wrench handle is greater than 15cm. The support rod's connection to the middle ensures force balance and stability during operation. The clearly defined minimum handle length ensures a sufficiently long lever arm, allowing the operator to generate a large pulling force with a small amount of force. This saves effort and is convenient to operate, optimizing the tool's ergonomic design, clarifying the key dimensional parameters for achieving the effort-saving effect, and enhancing the tool's practicality.

[0011] Optionally, the support rod is 14cm long, the pry bar is 3.5cm long, and the support rod, the bent part, and the pry bar are all made of DN15 stainless steel pipe. When disassembling the middle mold of the catalyst tableting machine, place the pry bar part of the wrench under the middle mold of the large plate, so that the bent part is under the middle mold, and gently press down on the wrench handle. The middle mold will be pushed out, making the disassembly process of the middle mold smoother and more efficient. It can be used on both sides of the machine, is easy to operate, and avoids scratching the equipment and causing damage during operation.

[0012] Optionally, both ends of the wrench handle are rotatably connected to rotating sleeves. The outer material of the rotating sleeves is silicone. By rotatably connecting the rotating sleeves to both ends of the wrench handle, the rotating sleeves can rotate relative to the wrench handle during the process of the user pressing down with their hand to disassemble the middle mold. This avoids damage caused by long-term friction between the palm and the wrench handle, making the operation of the wrench smoother and protecting the palm.

[0013] Optionally, the bending part is a rod-shaped structure with rounded corners, the bending angle of the bending part is 60 degrees, and a reinforcing rib is fixedly connected to the top of the bending part. By setting a reinforcing rib at the inner bending point of the bending part, the strength of the bending part is increased, enabling the wrench to withstand greater forces, avoiding the deformation of the bending part during the lifting of the central mold and affecting the subsequent disassembly efficiency, and enabling the wrench to achieve the same strength with less material, thereby reducing the production cost of the wrench.

[0014] Optionally, a sliding wheel is rotatably connected to the bottom of the bending part. The width of the sliding wheel is smaller than the diameter of the bending part. By setting the sliding wheel at the bottom of the bending part, the bottom of the bending part contacts the equipment through the sliding wheel during the process of the wrench being inserted into and pulled out, making the process of the wrench entering and being pulled out smoother and avoiding the situation where the bottom of the bending part of the wrench slides with the equipment and causes scratches.

[0015] Optionally, a protective ball is fixedly connected to the top of the end of the pry bar. The protective ball is made of hard silicone. By setting the protective ball at the end of the pry bar, the contact area between the equipment and the intermediate mold can be protected during the contact process between the end of the pry bar and the equipment, avoiding scratches during the lifting process. In addition, the protective ball made of hard silicone has a certain degree of corrosion resistance, preventing oil stains inside the equipment from corroding the protective ball.

[0016] Positive and beneficial effects:

[0017] 1. This special wrench for disassembling the middle mold of the catalyst industry tableting machine forms a basic tool form specifically for ejection operations in narrow spaces. Through the lever principle, the downward pressing action at the handle is converted into the upward ejection force at the pry bar, avoiding the inefficiency and safety hazards of traditional knocking methods, and providing a basic tool framework for solving the problem of middle mold disassembly.

[0018] 2. This special wrench for disassembling the middle mold of the catalyst tableting machine is designed for easy and efficient disassembly. When disassembling the middle mold of the catalyst tableting machine, place the pry bar of the wrench under the middle mold, with the bent part pressing against the bottom of the middle mold. Gently press down on the wrench handle, and the middle mold will be pushed out, making the disassembly process smoother and more efficient. It can be used on both sides of the machine, is easy to operate, and avoids scratching the equipment and causing damage during operation.

[0019] 3. This special wrench for disassembling the middle mold of the catalyst industry tableting machine has a reinforcing rib on the inner side of the bend to increase the strength of the bend. This allows the wrench to withstand greater forces and avoids deformation of the bend during the lifting of the middle mold, which would affect the subsequent disassembly efficiency. It also allows the wrench to achieve the same strength with less material, reducing the production cost of the wrench.

[0020] 4. This special wrench for disassembling the intermediate mold of the catalyst industry tableting machine has a protective ball at the end of the pry bar. When the end of the pry bar contacts the equipment, it can protect the contact area between the equipment and the intermediate mold, preventing scratches during the lifting process. In addition, the protective ball made of hard silicone has a certain degree of corrosion resistance, preventing oil stains inside the equipment from corroding the protective ball.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] Example 1

[0029] like Figures 1 to 5 As shown, a special wrench for disassembling the middle mold of a catalyst industry tableting machine includes a wrench handle 1, a support rod 2 fixedly connected to one side of the wrench handle 1, a bent part 3 fixedly connected to the end of the support rod 2, and a pry bar 4 fixedly connected to the end of the bent part 3. It forms a basic tool shape specifically for ejection operations in narrow spaces. Through the lever principle, the downward pressing action at the handle is converted into an upward ejection force at the pry bar, avoiding the inefficiency and safety hazards of traditional knocking methods, and providing a basic tool structure for solving the problem of middle mold disassembly.

[0030] like Figure 1 and Figure 2 As shown, the support rod 2 is fixedly connected to the middle of one side of the wrench handle 1. The length of the wrench handle 1 is greater than 15cm. The support rod's connection to the middle ensures force balance and stability during operation. The clearly defined minimum handle length ensures a sufficiently long lever arm, allowing the operator to generate a large pulling force with a small amount of force. This saves effort and is convenient to operate, optimizing the tool's ergonomic design, clarifying the key dimensional parameters for achieving the effort-saving effect, and enhancing the tool's practicality.

[0031] The support rod 2 is 14cm long, and the pry bar 4 is 3.5cm long. The support rod 2, the bent part 3, and the pry bar 4 are all made of DN15 stainless steel pipe. When disassembling the middle mold of the catalyst tableting machine, place the pry bar part of the wrench under the middle mold of the large plate, so that the bent part 3 is under the middle mold, and gently press down on the wrench handle 1. The middle mold will be pushed out, making the disassembly process of the middle mold smoother and more efficient. It can be used on both sides of the machine, is easy to operate, and avoids scratching the equipment and causing damage during operation.

[0032] Example 2

[0033] like Figures 2 to 4 As shown, both ends of the wrench handle 1 are rotatably connected to rotating sleeves 5. The outer material of the rotating sleeves 5 is silicone. By rotatably connecting the rotating sleeves 5 to both ends of the wrench handle 1, the rotating sleeves 5 can rotate relative to the wrench handle 1 during the process of the user pressing down with their hand to disassemble the middle mold. This avoids damage caused by long-term friction between the palm and the wrench handle 1, making the operation of the wrench smoother and protecting the palm.

[0034] like Figures 2 to 5 As shown, the bending part 3 is a rod-shaped structure with rounded corners. The bending angle of the bending part 3 is 60 degrees. A reinforcing rib 8 is fixedly connected to the top of the bending part 3. By setting the reinforcing rib 8 at the inner bending point of the bending part 3, the strength of the bending part 3 is increased, so that the wrench can withstand greater force. This avoids the bending part 3 from deforming during the process of lifting the middle mold, which would affect the subsequent disassembly efficiency. It also allows the wrench to achieve the same strength with less material, thus reducing the production cost of the wrench.

[0035] like Figures 2 to 5 As shown, a sliding wheel 6 is rotatably connected to the bottom of the bending part 3. The width of the sliding wheel 6 is smaller than the diameter of the bending part 3. By setting the sliding wheel 6 at the bottom of the bending part 3, the bottom of the bending part 3 contacts the equipment through the sliding wheel 6 during the process of the wrench being inserted into and pulled out, making the process of the wrench entering and being pulled out smoother and avoiding the situation where the bottom of the bending part 3 of the wrench slides with the equipment and causes scratches.

[0036] like Figure 2 and Figure 3 As shown, a protective ball 7 is fixedly connected to the top of the end of the pry bar 4. The protective ball 7 is made of hard silicone. By setting the protective ball 7 at the end of the pry bar 4, the contact parts between the equipment and the middle mold can be protected during the contact process between the end of the pry bar 4 and the equipment, avoiding scratches during the lifting process. In addition, the protective ball 7 made of hard silicone has a certain degree of corrosion resistance, preventing oil stains inside the equipment from corroding the protective ball 7.

[0037] The working principle of this utility model is as follows:

[0038] When disassembling the intermediate mold of the catalyst tableting machine, place the pry bar of the wrench under the intermediate mold of the large plate, so that the bent part is under the intermediate mold, and gently press down on the wrench handle. The intermediate mold will be pushed out, making the disassembly process of the intermediate mold smoother and more efficient. It can be used on both sides of the machine, is easy to operate, and avoids scratching the equipment and causing damage during operation.
